Hi All,

The latest mainline kernel branch fails to build alpha, csky and s390
allmodconfig with the error:

drivers/mfd/cs42l43.c:1138:12: error: 'cs42l43_runtime_resume' defined but not used [-Werror=unused-function]
1138 | static int cs42l43_runtime_resume(struct device *dev)

git bisect pointed to ace6d1448138 ("mfd: cs42l43: Add support for cs42l43 core driver")

I will be happy to test any patch or provide any extra log if needed.
