    Subject[PATCH AUTOSEL 5.5 099/542] mfd: max77650: Select REGMAP_IRQ in Kconfig
    Date
    From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

    [ Upstream commit cb7a374a5e7a5af3f8c839f74439193add6d0589 ]

    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.
