Subject: [PATCH] staging: rtl8723bs: Fix an error handling path
Date: Sun, 20 Jun 2021 10:21:31 +0200	[thread overview]
Message-ID: <a9533d1594900152e1e64e9f09e54240e3b7062a.1624177169.git.christophe.jaillet@wanadoo.fr> (raw)

'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")
