Re: [PATCH v2 1/2] power: supply: max17042_battery: Clear status bits in interrupt handler

The gauge requires us to clear the status bits manually for some alerts to be properly dismissed. Previously the IRQ was configured to react only on falling edge, which wasn't technically correct (the ALRT line is active low), but it had a happy side-effect of preventing interrupt storms on uncleared alerts from happening.
