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.
