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: - Fix rtw_debugfs_copy_from_user error code in first patch - Squash other patches to second patch Zhang Shurong (2): wifi: rtw88: fix incorrect error codes in rtw_debugfs_copy_from_user wifi: rtw88: fix incorrect error codes in rtw_debugfs_set_* drivers/net/wireless/realtek/rtw88/debug.c | 59 ++++++++++++++++------ 1 file changed, 43 insertions(+), 16 deletions(-) -- 2.40.0
