commit cb7a374a5e7a5af3f8c839f74439193add6d0589 upstream.
MAX77650 MFD driver uses regmap_irq API but doesn't select the required REGMAP_IRQ option in Kconfig. This can cause the following build error if regmap irq is not enabled implicitly by someone else:
ld: drivers/mfd/max77650.o: in function `max77650_i2c_probe': max77650.c:(.text+0xcb): undefined reference to `devm_regmap_add_irq_chip' ld: max77650.c:(.text+0xdb): undefined reference to `regmap_irq_get_domain' make: *** [Makefile:1079: vmlinux] Error 1
Fix it by adding the missing option.
