I am seeing the following Kconfig warning from ARCH=s390 allmodconfig:
WARNING: unmet direct dependencies detected for RTC_CLASS
Depends on [n]: !S390 [=y]
Selected by [m]:
- TURRIS_OMNIA_MCU [=m] && CZNIC_PLATFORMS [=y] && (MACH_ARMADA_38X || COMPILE_TEST [=y]) && I2C [=m] && OF [=y] && WATCHDOG [=y]
because of:
menuconfig RTC_CLASS
bool "Real Time Clock"
default n
depends on !S390
which appears to have ultimately come from commit 9556fb73edfc ("[S390]
Kconfig: unwanted menus for s390."). No other driver appears to
unconditionally select this (I only see it selected within
arch/*/Kconfig), so it does not look like this has come up before.
Should s390 be excluded from the COMPILE_TEST dependency?
Cheers,
Nathan
