[PATCH] scsi_lib: Delete unnecessary checks before two function calls

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
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.
