ste_dma40: Delete an unnecessary check before the function call “kmem_cache_destroy”
Author: Markus Elfring <elfring@users.sourceforge.net>
The kmem_cache_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
