Subject: arm64: select ARCH_WANT_OPTIONAL_GPIOLIB
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9170100ee46402af6d318134525c728027318d67;p=linux.git

arm64: select ARCH_WANT_OPTIONAL_GPIOLIB

An architecture should not unconditionally enable 'GENERIC_GPIO'
without providing an implementation. In case of arm64, selecting
ARCH_WANT_OPTIONAL_GPIOLIB is the right solution, because it
lets us enable GPIOLIB when configuring the kernel, and that
implicitly turns on GENERIC_GPIO.
