Subject: [PATCH] pwm: Make pwmchip_remove() return void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since some time pwmchip_remove() always returns 0 so the return value
isn't usefull. Now that all callers are converted to ignore its value
the function can be changed to return void.
