Subject: [PATCH 0/8] gpiolib cleanups

From: Arnd Bergmann <arnd@...db.de>

These are some older patches I did last year, rebased to linux-next-20230125.

The main goal is to remove some of the legacy bits of the gpiolib
interfaces, where the corner cases are easily avoided or replaced
with gpio descriptor based interfaces.

We seem to all be touching the same functions at the moement, let
me know if this conflicts with your work.
