From 687236b07a672ad10a0432270c7b19217580a0b1 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sat, 10 Aug 2019 12:17:26 +0200 Subject: [PATCH] qca: 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: "David S.
