From b8fc7743406d883e68d60ad6e73a86ae9059f1e6 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 29 May 2018 17:30:57 +0200 Subject: USB: ehci-hcd: 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.
