[PATCH 0/4] iio: hid-sensor: add module alias for autoload

[PATCH 0/4] iio: hid-sensor: add module alias for autoload

[Alexander Holler]

Hello,

I'm not sure if it was by intention that none of the hid-sensor drivers
were loaded automatically. But I assume it was not by intention.

Therefor I've added a module alias to every hid-sensor driver by adding
a MODULE_DEVICE_TABLE.

This has another benefit: it makes it possible to use a normale driver name.

Therefor I've changed all driver names to KBUILD_MODNAME instead of
HID-SENSOR-2000xx as the later isn't very descriptive when starring at
kernel messages.

Regards,

Alexander Holler

[PATCH 1/4] iio: hid-sensor-accel-3d: add module alias for autoload

[Alexander Holler]

Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically
load the driver.

This makes it also possible to use the usual driver name instead of
HID-SENSOR-2000xx which isn't very descriptive in kernel messages.

Hi,

There was no intention to prevent auto loading. Did you get chance to 
test these changes?

Thanks,

Sure, I always test patches before I send them out.

Ok, I haven't tested the changes with the iio HID drivers (I don't have 
any commercial HID sensor hub, so I've just compile tested these patches 
here, double reading them), but I've tested the similiar changes with a 
patch for rtc-hid-sensor-time I've send out yesterday. (sorry, no link, 
lkml.org seems dead, just search for "rtc-hid-sensor-time: add module 
alias")

It works just fine. An example output is now

Jul  9 19:27:21 dockstar3 kernel: [    5.124444] rtc_hid_sensor_time 
HID-SENSOR-2000a0.0: milliseconds supported
Jul  9 19:27:21 dockstar3 kernel: [    5.132864] rtc_hid_sensor_time 
HID-SENSOR-2000a0.0: rtc core: setting system clock to 2013-07-09 
17:26:51:328000 UTC (1373390811)
Jul  9 19:27:21 dockstar3 kernel: [    5.146105] rtc_hid_sensor_time 
HID-SENSOR-2000a0.0: rtc core: registered hid-sensor-time as rtc0

Before the output was e.g.

HID-SENSOR-2000a0 HID-SENSOR-2000a0.0: rtc core: registered 
hid-sensor-time as rtc0

instead of the above with the descriptive rtc_hid_sensor_time.

Automatic loading of modules works too and it works on ARM, Intel and 
AMD as module or static linked. ;)

Alexander Holler

Do you have tested the patches with a real device? I assume you have one. ;)

Just so you two know. Given this discussion, I'll be lazy about these and
wait for an Ack from Srinivas before taking these.  Look fine to me, but
nice to have confirmation as you say with the actual hardware!
