Date: Fri, 19 Nov 2010 21:41:40 +0300 From: Vasiliy Kulikov <segoon@...nwall.com> To: kernel-janitors@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...e.de>, linux-kernel@...r.kernel.org Subject: [PATCH] drivers: base: core: do not put noninitialized devices If kobject_set_name_vargs() fails then put_device() frees device with zero kobj->state_initialized. This leads to WARN(). Divide device_register() call to device_initialize() call before kobject_set_name_vargs() and device_add() call after it.
