Subject: [PATCH 5/9] driver core: remove device_create_vargs
Date: Mon,  4 May 2020 14:47:57 +0200	[thread overview]
Message-ID: <20200504124801.2832087-6-hch@lst.de> (raw)
In-Reply-To: <20200504124801.2832087-1-hch@lst.de>

All external users of device_create_vargs are gone, so remove it and
open code it in the only caller.
