From bb6abdd453e123bebdf949a03df5e846ecb5866b Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 15 Feb 2019 09:52:32 +0000 Subject: [PATCH] scsi: qla2xxx: remove redundant null check on pointer sess The null check on pointer sess and the subsequent call is redundant as sess is null on all the the paths that lead to the out_term2 label. Hence the null check and the call can be removed. Also remove the redundant setting of sess to NULL as this is not required now.
