Merge tag 'gpio-fixes-for-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio fixes from Bartosz Golaszewski:

 - fix wake-up interrupt support on gpio-mxc

 - zero the padding bytes in a structure passed to user-space in the
   GPIO character device

 - require HAS_IOPORT_MAP in two drivers that need it to fix a Kbuild
   issue
