Potential uninitialized variables in power: supply: rt5033_battery:

[Yizhuo Zhai]

Hi:

drivers/power/supply/rt5033_battery.c:

In function rt5033_battery_get_present(), variable "val" could be
uninitialized if regmap_read() returns -EINVAL. However, "val" is
used to decide the return value, which is potentially unsafe.

Also, we cannot simply return -EINVAL in rt5033_battery_get_present()
because it's not an acceptable return value.

Thanks for your time to check this case.
