[PATCH v3 0/2] wifi: rtw88: error codes fix patches
From: Zhang Shurong
Date: Wed Apr 26 2023 - 13:13:45 EST
rtw88 does not handle the failure during copy_from_user or invalid
user-provided data. We fix such problems by first modifying the return
value of customized function rtw_debugfs_copy_from_user. Then for all
the callers rtw_debugfs_set_*, we receive the returned error code.
Moreover, negative code is returned if the user-provided data is invalid
instead of a positive value count.
The changes in this version:
- check by if (ret) instead of check by if (ret < 0)
