[ARM] 5141/1: PWM: pwm_request() should return an PTR_ERR() instead of NULL.
Make the return of pwm_request() be more informative than just being NULL on error by using PTR_ERR() to respond with an approriate error. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
