[PATCH] s390/pci: Remove unnecessary if condition

From: Amitoj Kaur Chawla
Date: Fri Jul 29 2016 - 04:32:04 EST


Remove unnecessary error handling because the only failure value that
can be returned is NULL and so the test can never be true.

The Coccinelle semantic patch used to make this change is as follows:
@@
expression e;
@@

e = debugfs_create_file(...);
- if(IS_ERR(e)) { e = NULL; }
