[PATCH 3/3] spi: qup: Remove .owner field for driver

[PATCH 3/3] spi: qup: Remove .owner field for driver

[Kiran Padwal]

There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superfluous .owner field for drivers which
use the module_platform_driver API, as this is overridden in
platform_driver_register anyway."

Two problems:
 - I'm missing patches 1 and 2.
 - This only changes one driver but essentially every SPI driver
   initializes .owner - why is only thi sone driver being changed?

These patches are same like this one,
[1] https://lkml.org/lkml/2014/10/9/58
[2] https://lkml.org/lkml/2014/10/9/52

Nothing more intention, but just remove superfluous .owner field for drivers which
use the module_platform_driver API, as this is overridden in
platform_driver_register anyway.

You should at least be sending the cover letter to everyone so that they
know what's going on.

My point is that doing a change like this to random drivers isn't great,
if you're going to do this sort of thing it is better to do it for
everything rather than making things inconsistent.

OK, I will take care of this next time.
