Merge tag 'gpio-v5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Some GPIO fixes I've collected with the help of Bartosz.

  Nothing special about them: all are driver and kbuild fixes + some
  documentation fixes:

   - Tidy up a missed function call in the designware driver when
     converting to gpiolib irqchip

   - Fix some bitmasks in the Aspeed driver

   - Fix some kerneldoc warnings and minor bugs in the improved
     userspace API documentation

   - Revert the revert of the OMAP fix for lost edge wakeup interrupts:
     the fix needs to stay in

   - Fix a compile error when deselecting the character device

   - A bunch of IRQ fixes on the idio GPIO drivers

   - Fix an off-by-one error in the SiFive GPIO driver"
