From 519e96ee114ff70e420111b39d884153250626dd Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 22 Jan 2019 15:35:41 +0100 Subject: x86: platform: no need to check return value of debugfs_create functions 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. Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Borislav Petkov Cc: "H.
