From 1d8f95c497053839be326bd97eb3128e3b3312cb Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 18 Aug 2020 15:36:07 +0200 Subject: media: radio: si476x: 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.
