[ Upstream commit 43d15c2013130a9fa230c2f5203aca818ae0bb86 ]
The kbuild test robot reports the following: drivers/staging//rtlwifi/phydm/phydm_dig.c: In function 'odm_pause_dig': drivers/staging//rtlwifi/phydm/phydm_dig.c:494:45: warning: array subscript is below array bounds [-Warray-bounds] odm_write_dig(dm, dig_tab->pause_dig_value[max_level]);
This condition is caused when a loop falls through. The fix is to pin max_level to be >= 0.
