EDAC: Do not 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. [ bp: Make edac_debugfs_init() return void too, while at it. ] Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: James Morse <james.morse@arm.com> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: linux-edac <linux-edac@vger.kernel.org> Link: https://lkml.kernel.org/r/20190122152151.16139-17-gregkh@linuxfoundation.org
