Linus Torvalds 8841842cc9 pwm: Two driver fixes
After having added some more code to libpwm checking the pwm rounding
 rules for the userspace interface I spotted an issue in the pwm-stm32
 driver where in some cases involving inverted polarity the wrong
 hardware settings for the duty offset are chosen. I think it has little
 practical effect because the duty offset is in most cases an artificial
 property of the output waveform. Still it's relevant to get this fixed
 because this driver serves as a reference implementation for the still
 young waveform API.
 
 The second fix addresses a sleep-in-atomic issue in the pwm-atmel-tcb
 driver.
