From 40d796243478e0d072a7e637e7558c3c8216b60a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 11 Jun 2019 19:54:33 +0200 Subject: [PATCH] EDAC: Make edac_debugfs_create_x*() return void The return values of edac_debugfs_create_x16() and edac_debugfs_create_x8() are never checked (as they don't need to be), so no need to have them return anything, just make the functions return void instead. This is done with the goal of being able to change the debugfs_create_x* functions to also not return a value.
