[PATCH 0/2] pwm: Manage owner assignment implicitly for drivers

Hello,

while working on the pwm core I noticed that pwm-crc doesn't assign
.owner in its pwm_ops structure. This isn't a problem in practise though
as this driver can only be compiled built-in (up to now).

Still prevent future pwm drivers not assigning .owner by wrapping
pwmchip_add() in a macro that automates owner handling simplifying each
driver a (tiny) bit.

I also found that there is no hard reason to only compile pwm-crc as a
built-in on x86, so this limitation is lifted in the second patch.

Best regards
Uwe
