From 362c571b92e2fa734c1f2c1e303d1dc27f12ec95 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Mon, 12 Aug 2019 18:27:40 +0200 Subject: HID: wacom: do not call hid_set_drvdata(hdev, NULL) This is a common pattern in the HID drivers to reset the drvdata. However, this is actually already handled by driver core, so there is no need to do it manually.
