[PATCH 5.16 0513/1017] iwlwifi: Fix -EIO error code that is never returned

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

[ Upstream commit c305c94bdc18e45b5ad1db54da4269f8cbfdff6b ]

Currently the error -EIO is being assinged to variable ret when
the READY_BIT is not set but the function iwlagn_mac_start returns
0 rather than ret. Fix this by returning ret instead of 0.

Addresses-Coverity: ("Unused value")
Fixes: 7335613ae27a ("iwlwifi: move all mac80211 related functions to one place")
