From 8c080bd0a1f9f337add122e1c0252151a8f89c14 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 22 Nov 2014 15:00:55 +0100 Subject: [PATCH] s390/pci: Deletion of unnecessary checks before the function call "debug_unregister" The debug_unregister() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
