Subject: [PATCH][Trivial] lib/kobject.c: Remove redundant check in populate_dir
Date: Sat, 21 Apr 2012 18:18:25 +0800 [thread overview]
Message-ID: <1335003508.2188.44.camel@yan> (raw)
create_dir will call sysfs_create_dir and then populate_dir.
If ktype of kobject is null, sysfs_craete_dir will lead to
oops first. There is no need to check ktype in populate_dir.
