From a18591ff06fe7a26d30c2653ad54572fa89aaff5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2795/2940] amdkfd: no need to check return value of
debugfs_create functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
