From ef6687c627a5338f1fbea134efca6e7f479cd70c Mon Sep 17 00:00:00 2001 From: Luis de Bethencourt Date: Mon, 27 Jun 2016 14:00:20 +0100 Subject: [PATCH] staging: wilc1000: fix error handling in wilc_debugfs_init() We can just ignore the return value from debugfs_create_dir() and debugfs_create_file(). The second one already interanlly checks the dentry created by the first before creating the file. debugfs was written so it would be easy to use, no need for error checking.
