When building on ARCH=um (which does not set HAS_IOMEM), kconfig
reports an unmet dependency caused by PINCTRL_STMFX. It selects
MFD_STMFX, which depends on HAS_IOMEM. To stop this warning,
PINCTRL_STMFX should also depend on HAS_IOMEM.
kconfig warning:
WARNING: unmet direct dependencies detected for MFD_STMFX
Depends on [n]: HAS_IOMEM [=n] && I2C [=y] && OF [=y]
Selected by [y]:
- PINCTRL_STMFX [=y] && PINCTRL [=y] && I2C [=y] && OF_GPIO [=y]
