Subject: [PATCH] scsi: pcmcia: fdomain: Fix an error code in probe()
Date: Tue, 10 Aug 2021 11:47:00 +0300 [thread overview]
Message-ID: <20210810084700.GC23810@kili> (raw)
If request_region() fails, the driver should return -EBUSY but this
code accidentally returns success.
Fixes: 8674a8aa2c39 ("scsi: fdomain: Add PCMCIA support")
