Return-Path: From: David Herrmann To: linux-bluetooth@vger.kernel.org Cc: johan.hedberg@gmail.com, marcel@holtmann.org, David Herrmann Subject: [PATCH 2/4] Bluetooth: Remove hci_dev->driver_data Date: Fri, 27 Jan 2012 16:47:24 +0100 Message-Id: <1327679246-2667-3-git-send-email-dh.herrmann@googlemail.com> In-Reply-To: <1327679246-2667-1-git-send-email-dh.herrmann@googlemail.com> References: <1327679246-2667-1-git-send-email-dh.herrmann@googlemail.com> List-ID: The linux device model provides dev_set/get_drvdata so we can use this to save private driver data. This also removes several unnecessary casts.
