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