[PATCH v2 00/10] Fix deferred probing in the USB host/gadget drivers

[Sergey Shtylyov]

Here are 10 patches against the 'usb-linus' branch of Greg KH's 'usb.git'
repo. The affected host/gadget drivers call platform_get_irq() but override
its result in case of error which prevents the deferred probing from working.
These patches now logically depend on the previously posted patch:

[PATCH v2 01/10] usb: gadget: udc: bcm63xx: fix deferred probing

[Sergey Shtylyov]

The driver overrides the error codes returned by platform_get_irq() to
-ENXIO for some strange reason, so if it returns -EPROBE_DEFER, the driver
will fail the probe permanently instead of the deferred probing. Switch to
propagating the error codes upstream.

   Argh, I missed this! :-(
   The whole series should be discarded, as the patch #8 also doesn't have the valid
