Subject: iwlwifi: mvm: return the actual error code when switch_vif_chanctx fails
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6fd1fb63abeb78fd7fe30f08f478732ad601702c;p=linux-beck.git

iwlwifi: mvm: return the actual error code when switch_vif_chanctx fails

We have code to recover and go back to the original channel context if
something fails in the middle of switch_vif_chanctx, but we return the
error code of the recover calls instead of the original code, so if
the recovery succeeds, we will return 0 (success).  Fix this by not
assigning the return value of the recovery calls to ret.
