[PATCH AUTOSEL 4.4 6/8] kobject: Drop unneeded conditional in __kobject_del()

[Sasha Levin]

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ Upstream commit 07ecc6693f9157cf293da5d165c73fb28fd69bf4 ]

__kobject_del() is called from two places, in one where kobj is dereferenced
before and thus can't be NULL, and in the other the NULL check is done before
call. Drop unneeded conditional in __kobject_del().
