Subject[PATCH] pinctrl: mediatek: fix build errors for moore core when CONFIG_OF is not enabled
Date
on i386 or x86_64:

Lots of build errors for drivers/pinctrl/mediatek/pinctrl-moore.c when
CONFIG_OF is not enabled (but COMPILE_TEST is).

first this:
WARNING: unmet direct dependencies detected for PINCTRL_MTK_MOORE
Depends on [n]: PINCTRL [=y] && (ARCH_MEDIATEK || COMPILE_TEST [=y]) && OF [=n]
Selected by [y]:
- PINCTRL_MT7623 [=y] && PINCTRL [=y] && (ARCH_MEDIATEK || COMPILE_TEST [=y]) && (MACH_MT7623 || COMPILE_TEST [=y])

and then:
