From 177709c0702e7351dae3b9b4f9de3140a9ee3a06 Mon Sep 17 00:00:00 2001 From: Lin Yi Date: Tue, 25 Jun 2019 10:34:16 +0800 Subject: [PATCH] scsi: bnx2fc: fix bnx2fc_cmd refcount imbalance in send_rec If cb_arg alloc failed, we can't release the struct orig_io_req refcount before we take its refcount. As Saurav said, move the rec_err label down to avoid unnecessary refcount release and nullptr free. Signed-off-by: Lin Yi Acked-by: Saurav Kashyap Signed-off-by: Martin K.
