Subject: [PATCH] power_supply: max17042: Use regmap_update_bits instead read
 and write

Consolidate regmap_read() and regmap_write() into one
regmap_update_bits() call. This is more readable and safer because
regmap's mutex will prevent any concurrent access to modified registers
(the concurrent access could happen through max17042_init_chip() in
scheduled work).
