From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
[ Upstream commit c9eaee0c2ec6b1002044fb698cdfb5d9ef4ed28c ]
The sscanf() function returns the number of matches (0 or 1 in this
case). It doesn't return error codes. We should return -EINVAL if the
string is invalid
Fixes: c376c1fc87b7 ("rtw88: add h2c command in debugfs")
