[PATCH 5.13 750/800] staging: rtl8723bs: Fix an error handling path
From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 05:04:14 EST
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit eb64c6f60ed5406da496cf772fee4b29674bcbb1 ]
'ret' is known to be 0 at this point. It must be set to -ENOMEM if a
memory allocation occurs.
Fixes: 554c0a3abf21 ("staging: Add rtl8723bs sdio wifi driver")
