Subject: [PATCH] iwlwifi: Fix -EIO error code that is never returned
Date:   Tue,  7 Sep 2021 11:46:58 +0100

From: Colin Ian King <colin.king@canonical.com>

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")
