[PATCH] Drop owner assignment from i2c_driver (and platform left-overs)

[PATCH] Drop owner assignment from i2c_driver (and platform left-overs)

[Krzysztof Kozlowski]

Hi,


The i2c drivers also do not have to set 'owner' field because
i2c_register_driver() will do it instead.

'owner' is removed from i2c drivers, which I was able to compile
with allyesconfig (arm, arm64, i386, x86_64, ppc64).
Only compile-tested.

The coccinelle script which generated the patch was sent here:
http://www.spinics.net/lists/kernel/msg2029903.html


Best regards,
Krzysztof

[PATCH] drm: Drop owner assignment from i2c_driver

[Krzysztof Kozlowski]

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

But rockchip drm is platform driver not i2c_driver, why remove its .owner ?

Oh, indeed. Thanks for spotting this.

The 'owner' is set by core for platform drivers as well. Most platform
drivers were already converted (I think by Wolfram Sang). I extended
existing coccinelle script to fix also i2c_drivers and sometimes did not
notice that it was platform_driver.

I can split it into two different patches. Would that be ok?

Best regards,
Krzysztof
