Conor Dooley found and fixed a problem in the pwm-microchip-core driver that existed since the driver's birth in v6.5-rc1. It's about a corner case that only happens if two pwm devices of the same chip are set to the same long period. The other problem is about the new pwm API that currently is only supported by two hardware drivers. The fix prevents a NULL pointer exception if one of the new functions is called for a pwm device with a driver that only provides the old callbacks. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmeXs+8ACgkQj4D7WH0S /k4zqQgAs6b6PWu99Bh59WbLtqdpo3GfBrxXEGajYfG/rl/WCqTaaR0drQGE+Mlz oqJrJ9klO02JcnPh7tyUi8oIDGm+zJ5Y6au60Ry5aDvZCh370RlXWrqaVJO9dK1k rWfko7rI2/7LFmrpn9Ass/RNjWcL2c/7C9b+NiXfrHlcgdSq49tjBziN6adCOnrF NtOjnAD9jalVxHEaS9z3rhdE714XLvR/NtevzQX5fp9rZylENKrVta0FZnJMX7uD OE6OhsxSyo4nuVpHgL9YLg45JTgzHzIyCJ+GTO0Cjk9oD1UHBKxiv2zOw5j4tBt4 PAQ/yZ10kwJ9IF4j8bxTFYg3PLItLQ== =EWDl -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.14-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: "Two fixes.
