From 7e9f02a7896bf12bddfa28c4fdc442aa6cc6eda1 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 11 Jun 2019 20:43:23 +0200 Subject: mic: 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.
