Subject[PATCH 1/3] extcon: max8997: select IRQ_DOMAIN instead of depending on it
Date
IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set
it directly thru "make *config", so drivers should select it instead
of depending on it if they need it.
Relying on it being set for a dependency is risky.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change EXTCON_MAX8997's use of "depends on" for
IRQ_DOMAIN to "select".

Fixes: dca1a71e4108 ("extcon: Add support irq domain for MAX8997 muic")

If you say yes here you get support for the MUIC device of
Maxim MAX8997 PMIC. The MAX8997 MUIC is a USB port accessory
