Subject: [PATCH] scsi: acornscsi: Fix an error handling path in 'acornscsi_probe()'
Date: Sat, 30 May 2020 10:16:22 +0200
Message-ID: <20200530081622.577888-1-christophe.jaillet@wanadoo.fr> (raw)

'ret' is known to be 0 at this point.
So, explicitly return -ENOMEM if one of the 'ecardm_iomap()' calls fail.

Fixes: e95a1b656a98 ("[ARM] rpc: acornscsi: update to new style ecard driver")
