Sigh, it was a copy and paste error when I copied the SHA-1 from the
commit message. Sorry about that and thanks for taking care of this.

The fixes line should be:

Fixes: 7311ea850079 ("mwifiex: fix AP start problem for newly added interface")

I can fix that before I apply the patch.

Looks correct to me as Dan Carpenter submitted the same fix.

[PATCH] mwifiex: fix unconditional error return in .add_virtual_intf callback

[Javier Martinez Canillas]

The commit 7311ea850079 ("mwifiex: fix AP start problem for newly added
interface") attempted to fix an issue when a new AP interface is added.

But the patch didn't check the return value of the functions doing the
firmware calls and returned an error even if the functions didn't fail.

This prevents the network device to be registered properly, so fix it.

Fixes: commit 7311ea850079 ("mwifiex: fix AP start problem for newly added 
interface")
