Merge tag 'gpio-v4.12-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull last minute fixes for GPIO from Linus Walleij:
- Fix another ACPI problem with broken BIOSes.
- Filter out the right GPIO events, making a very user-visible bug go
away.
* tag 'gpio-v4.12-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: acpi: Skip _AEI entries without a handler rather then aborting the scan
gpiolib: fix filtering out unwanted events
