Hi All: drivers/net/ethernet/hisilicon/hip04_eth.c:
In function hip04_reset_ppe(), variable "val" could be uninitialized if regmap_read() returns -EINVAL. However, "val" is used to decide the control flow, which is potentially unsafe. Also, we cannot simply return -EINVAL in hip04_reset_ppe() because the return type is void. Thanks for your time to check this case. -- Kind Regards, Yizhuo Zhai Computer Science, Graduate Student University of California, Riverside
