Subject: [PATCH] scsi_lib: Delete unnecessary checks before two function calls
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 17 Nov 2015 09:00:31 +0100
The functions kmem_cache_destroy() and mempool_destroy() test whether
their argument is NULL and then return immediately.
Thus the tests around their calls are not needed.
This issue was detected by using the Coccinelle software.
