[PATCH 3.10 01/20] DRM - radeon: Dont link train DisplayPort on HPD until we get the dpcd

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Chandler Paul <cpaul@redhat.com>

commit 924f92bf12bfbef3662619e3ed24a1cea7c1cbcd upstream.

Most of the time this isn't an issue since hotplugging an adaptor will
trigger a crtc mode change which in turn, causes the driver to probe
every DisplayPort for a dpcd. However, in cases where hotplugging
doesn't cause a mode change (specifically when one unplugs a monitor
from a DisplayPort connector, then plugs that same monitor back in
seconds later on the same port without any other monitors connected), we
never probe for the dpcd before starting the initial link training. What
happens from there looks like this:

	- GPU has only one monitor connected. It's connected via
	  DisplayPort, and does not go through an adaptor of any sort.

	- User unplugs DisplayPort connector from GPU.

	- Change in HPD is detected by the driver, we probe every
	  DisplayPort for a possible connection.

	- Probe the port the user originally had the monitor connected
	  on for it's dpcd. This fails, and we clear the first (and only
	  the first) byte of the dpcd to indicate we no longer have a
	  dpcd for this port.

	- User plugs the previously disconnected monitor back into the
	  same DisplayPort.

	- radeon_connector_hotplug() is called before everyone else,
	  and tries to handle the link training. Since only the first
	  byte of the dpcd is zeroed, the driver is able to complete
	  link training but does so against the wrong dpcd, causing it
	  to initialize the link with the wrong settings.

	- Display stays blank (usually), dpcd is probed after the
	  initial link training, and the driver prints no obvious
	  messages to the log.

In theory, since only one byte of the dpcd is chopped off (specifically,
the byte that contains the revision information for DisplayPort), it's
not entirely impossible that this bug may not show on certain monitors.
For instance, the only reason this bug was visible on my ASUS PB238
monitor was due to the fact that this monitor using the enhanced framing
symbol sequence, the flag for which is ignored if the radeon driver
thinks that the DisplayPort version is below 1.1.

[PATCH 3.10 03/20] iio: Add inverse unit conversion macros

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@metafoo.de>

commit c689a923c867eac40ed3826c1d9328edea8b6bc7 upstream.

Add inverse unit conversion macro to convert from standard IIO units to
units that might be used by some devices.

Those are useful in combination with scale factors that are specified as
IIO_VAL_FRACTIONAL. Typically the denominator for those specifications will
contain the maximum raw value the sensor will generate and the numerator
the value it maps to in a specific unit. Sometimes datasheets specify those
in different units than the standard IIO units (e.g. degree/s instead of
rad/s) and so we need to do a unit conversion.

>From a mathematical point of view it does not make a difference whether we
apply the unit conversion to the numerator or the inverse unit conversion
to the denominator since (x / y) / z = x / (y * z). But as the denominator
is typically a larger value and we are rounding both the numerator and
denominator to integer values using the later method gives us a better
precision (E.g. the relative error is smaller if we round 8000.3 to 8000
rather than rounding 8.3 to 8).

This is where in inverse unit conversion macros will be used.

Marked for stable as used by some upcoming fixes.

In fixup_ti816x_class(), we assigned "class = PCI_CLASS_MULTIMEDIA_VIDEO".
But PCI_CLASS_MULTIMEDIA_VIDEO is only the two-byte base class/sub-class
and needs to be shifted to make space for the low-order interface byte.

Shift PCI_CLASS_MULTIMEDIA_VIDEO to set the correct class code.

[PATCH 3.10 09/20] usb: dwc3: ep0: Fix mem corruption on OUT transfers of more than 512 bytes

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kishon Vijay Abraham I <kishon@ti.com>

commit b2fb5b1a0f50d3ebc12342c8d8dead245e9c9d4e upstream.

DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
the size of bounce buffer is 512 bytes. However if the host initiates OUT
transfers of size more than 512 bytes (and non max packet aligned), the
driver throws a WARN dump but still programs the TRB to receive more than
512 bytes. This will cause bounce buffer to overflow and corrupt the
adjacent memory locations which can be fatal.

Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
(512) bytes.

Currently context size (cra_ctxsize) doesn't specified for
ghash_async_alg. Which means it's zero. Thus crypto_create_tfm()
doesn't allocate needed space for ghash_async_ctx, so any
read/write to ctx (e.g. in ghash_async_init_tfm()) is not valid.

[PATCH 3.10 13/20] HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_error

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Don Zickus <dzickus@redhat.com>

commit 3af4e5a95184d6d3c1c6a065f163faa174a96a1d upstream.

It was reported that after 10-20 reboots, a usb keyboard plugged
into a docking station would not work unless it was replugged in.

Using usbmon, it turns out the interrupt URBs were streaming with
callback errors of -71 for some reason.  The hid-core.c::hid_io_error was
supposed to retry and then reset, but the reset wasn't really happening.

The check for HID_NO_BANDWIDTH was inverted.  Fix was simple.

Tested by reporter and locally by me by unplugging a keyboard halfway until I
could recreate a stream of errors but no disconnect.

call12 can't be safely used as the first call in the inline function,
because the compiler does not extend the stack frame of the bounding
function accordingly, which may result in corruption of local variables.

If a call needs to be done, do call8 first followed by call12.

commit bab383de3b84e584b0f09227151020b2a43dc34c upstream.

parport_find_base() will implicitly do parport_get_port() which
increases the refcount. Then parport_register_device() will again
increment the refcount. But while unloading the module we are only
doing parport_unregister_device() decrementing the refcount only once.
We add an parport_put_port() to neutralize the effect of
parport_get_port().

[PATCH 3.10 19/20] drivercore: Fix unregistration path of platform devices

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Grant Likely <grant.likely@linaro.org>

commit 7f5dcaf1fdf289767a126a0a5cc3ef39b5254b06 upstream.

The unregister path of platform_device is broken. On registration, it
will register all resources with either a parent already set, or
type==IORESOURCE_{IO,MEM}. However, on unregister it will release
everything with type==IORESOURCE_{IO,MEM}, but ignore the others. There
are also cases where resources don't get registered in the first place,
like with devices created by of_platform_populate()*.

Fix the unregister path to be symmetrical with the register path by
checking the parent pointer instead of the type field to decide which
resources to unregister. This is safe because the upshot of the
registration path algorithm is that registered resources have a parent
pointer, and non-registered resources do not.

* It can be argued that of_platform_populate() should be registering
  it's resources, and they argument has some merit. However, there are
  quite a few platforms that end up broken if we try to do that due to
  overlapping resources in the device tree. Until that is fixed, we need
  to solve the immediate problem.

defconfig and allmodconfig with xtensa failed. With 3.10.88-rc1 I reported
that 123f15e669d5 ("xtensa: don't use echo -e needlessly") is required to fix
the build failure.

Note that it probably only fails to build for you because you use dash
as default shell.

I know it's a bit too late as this kernel has been released already,
but this patch doesn't look right to me.  The original patch is
changing the BMG160 driver, not the ITG3200.

The same applies to the 3.14 kernel -- it's changing the wrong
driver.

Cheers,

Thanks, this is right. I didn't notice this but the driver was
introduced in 3.18:
	22b46c45fb9b (iio:gyro:bmg160 Gyro Sensor driver)
