From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wolfram Sang Subject: [PATCH 1/1] hid: hid-sensor-custom: simplify getting .driver_data Date: Tue, 19 Mar 2019 17:36:38 +0100 Message-ID: <20190319163638.31003-1-wsa+renesas@sang-engineering.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: linux-renesas-soc@vger.kernel.org, Wolfram Sang , Jiri Kosina , Jonathan Cameron , Srinivas Pandruvada , Benjamin Tissoires , linux-input@vger.kernel.org, linux-iio@vger.kernel.org List-Id: linux-input@vger.kernel.org We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth.
