power: supply: bq256xx: fix some problem in bq256xx_hw_init
[ Upstream commit b55d073e6501dc6077edaa945a6dad8ac5c8bbab ]
smatch complains that there is a buffer overflow and clang complains
'ret' is never read.
Smatch error:
drivers/power/supply/bq256xx_charger.c:1578 bq256xx_hw_init() error:
buffer overflow 'bq256xx_watchdog_time' 4 <= 4
Clang static checker:
Value stored to 'ret' is never read.
Add check for buffer overflow and error code from regmap_update_bits().
Fixes: 32e4978bb920 ("power: supply: bq256xx: Introduce the BQ256XX charger driver")
