#     Merge tag 'gpio-v5.5-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
#     
#     Pull GPIO fixes from Linus Walleij:
#      "This reverts the GPIOLIB_IRQCHIP in the ThunderX driver.
#     
#       ThunderX is a piece of Arm-based server chip. I converted the driver
#       to hierarchical gpiochip without access to real silicon and failed
#       miserably since I didn't take MSI's into account.
#     
#       Kevin Hao helpfully stepped in and fixed it properly, let's revert it
#       for v5.5 and put the proper conversion into v5.6"
