From 60b8cabd8e8a1d266aa8778957691cd925673083 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 26 Oct 2007 20:07:44 +0200 Subject: [PATCH] Driver Core: fix bug in device_rename() for SYSFS_DEPRECATED=y This should fix the sysfs warnings that renaming network devices is causing to show up with CONFIG_SYSFS_DEPRECATED=y The code just shouldn't run if class devices are real directories, it's an update for the symlink in the class directory. Nobody noticed that as long as the creation of sysfs files silently failed, and we both missed it before the merge, because we don't run SYSFS_DEPRECATED=y.
