Subject: [PATCH 5/6] powerpc: cell: axon_msi: no need to check return value of debugfs_create functions

From: Greg Kroah-Hartman <[email-masked]>
Date: Sun, 9 Feb 2020 11:59:00 +0100

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.
