From e0241fb0b94399bb4131da7f29dc92cf5dc1ae71 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 3 Jun 2019 21:47:54 +0200 Subject: [PATCH] block: aoe: 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: "Ed L.
