Subject: [PATCH 1/1] hid: hid-sensor-custom: simplify getting .driver_data
Date: Tue, 19 Mar 2019 17:36:38 +0100	[thread overview]
Message-ID: <20190319163638.31003-1-wsa+renesas@sang-engineering.com> (raw)

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

Build tested only. buildbot is happy.
