Merge tag 'pwm/for-5.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry...

Pull pwm fixes from Thierry Reding:
 "It turned out that relying solely on drivers storing all the PWM state
  in hardware was a little premature and causes a number of subtle (and
  some not so subtle) regressions. Revert the offending patch for now"

* tag 'pwm/for-5.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  Revert "pwm: Let pwm_get_state() return the last implemented state"
