Hi Anton,

After merging the final tree, today's linux-next build (s390 allyesconfig)
failed like this:

drivers/built-in.o: In function `max8903_remove':
drivers/power/max8903_charger.c:355: undefined reference to `free_irq'
drivers/power/max8903_charger.c:357: undefined reference to `free_irq'
drivers/power/max8903_charger.c:359: undefined reference to `free_irq'

Caused by commit b14a9ccc1ddd ("power_supply: Add driver for MAX8903
charger").  This driver needs some Kconfig dependency.
