From b9d4e714a86a4e88c2f530c76597f7025e5851d6 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 4 Jan 2012 15:05:10 -0800 Subject: [PATCH] driver core: remove __must_check from device_create_file With the conversion of the sysdev to a real struct device, more drivers are calling device_create_file, and some of them don't check the return value, which isn't wise. But as they happen to be in parts of the kernel where a warning is considered an error (i.e. powerpc), this breaks the build. So for now, remove the marking on the function, which fixes the build problems.
