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. -- Kind Regards, Yizhuo Zhai Computer Science, Graduate Student University of California, Riverside
