#     Merge tag 'gpio-fixes-for-v5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
#     
#     Pull gpio fixes from Bartosz Golaszewski:
#      "Fix the same error check issue in two drivers. And then the drivers
#       are fixed even more because the first patches were incomplete which I
#       missed.
#     
#       Summary:
#     
#        - fix the error checks of platform_get_irq() in gpio-mpc8xxx and
#          gpio-idt3243x"
