Subject: pwm: Constify PWM device where possible
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a1cf42171a2e3c33cbc12bb037795caf0589149b;p=deliverable%2Flinux.git

pwm: Constify PWM device where possible

The PWM argument is not modified in PWM property accessors, make it a
const argument so that the accessors can be used from sysfs.
