From 77f9f7721866c97ea6314e05a83d50fc97bb5b1c Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 19 Mar 2019 17:36:38 +0100 Subject: [PATCH] HID: hid-sensor-custom: simplify getting .driver_data We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth.
