Subject: [PATCH 17/61] hid: simplify getting .drvdata
Date:   Thu, 19 Apr 2018 16:05:47 +0200
Message-Id: <20180419140641.27926-18-wsa+renesas@sang-engineering.com>
In-Reply-To: <20180419140641.27926-1-wsa+renesas@sang-engineering.com>
References: <20180419140641.27926-1-wsa+renesas@sang-engineering.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
