From 2d76a2478bb8c54d241b23a699d55f90b7efd036 Mon Sep 17 00:00:00 2001 From: Quentin Lambert Date: Sat, 19 Nov 2016 18:43:18 +0100 Subject: [PATCH] scsi: pmcraid: Add missing resource releases Most error branches following the call to pmcraid_get_free_cmd contain a call to pmcraid_return_cmd. This patch add these calls where they are missing. Moreover, most error branches following the call to class_create contain a call to class_destroy. This patch add these calls where they are missing. This issue was found with Hector. Signed-off-by: Quentin Lambert Reviewed-by: Tomas Henzl Signed-off-by: Martin K.
