hwmon: (ina3221) Do not read-back to cache reg_config
Reading back the CONFIG register increases an extra I2C transaction. This's not necessary and could be replaced with a local variable caching the register settings. So this patch replaces two readback regmap_read() calls with a tmp variable. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
