Date: Thu, 21 Nov 2013 20:15:48 +0100 From: David Herrmann <dh.herrmann@...il.com> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, David Herrmann <dh.herrmann@...il.com> Subject: [PATCH] driver core: fix device_create() error path We call put_device() in the error path, which is fine for dev==NULL. However, in case kobject_set_name_vargs() fails, we have dev!=NULL but device_initialized() wasn't called, yet. Fix this by splitting device_register() into explicit calls to device_add() and an early call to device_initialize().
