[PATCH v4 7/7] power: bq24190_charger: Handle fault before status on interrupt

[Liam Breck <liam@networkimprov.net>]

Reading both fault and status registers and logging any fault should
take priority over handling status register update.

Fix by moving the status handling to later in interrupt routine.
