For the arch/arm*/Kconfig and include/asm-generic changes:

Acked-by: Arnd Bergmann <arnd@arndb.de>

sta2x11 is an x86 driver, so not my area, but I think it would be
best to kill off the entire platform rather than just its gpio
driver, since everything needs to work together and it's clearly
not functional at the moment.

$ git grep -l STA2X11
Documentation/admin-guide/media/pci-cardlist.rst
arch/x86/Kconfig
arch/x86/include/asm/sta2x11.h
arch/x86/pci/Makefile
arch/x86/pci/sta2x11-fixup.c
drivers/ata/ahci.c
drivers/gpio/Kconfig
drivers/gpio/Makefile
drivers/gpio/gpio-sta2x11.c
drivers/i2c/busses/Kconfig
drivers/media/pci/Makefile
drivers/media/pci/sta2x11/Kconfig
drivers/media/pci/sta2x11/Makefile
drivers/media/pci/sta2x11/sta2x11_vip.c
drivers/media/pci/sta2x11/sta2x11_vip.h
drivers/mfd/Kconfig
drivers/mfd/Makefile
drivers/mfd/sta2x11-mfd.c
include/linux/mfd/sta2x11-mfd.h

Removing the other sta2x11 bits (mfd, media, x86) should
probably be done through the respective tree, but it would
be good not to forget those.
