Merge tag 'pwm/for-6.11-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux
Pull pwm fix from Uwe Kleine-König:
"Fix an off-by-one in the stm32 driver.
Hardware engineers tend to start counting at 1 while the software guys
usually start with 0. This isn't so nice because that results in
drivers where pwm device #2 needs to use the hardware registers with
index 3.
This was noticed by Fabrice Gasnier.
A small patch fixing that mismatch is the only change included here"
