Subject: [PATCH 1/7] HID: hiddev: use hid_hw_open/close instead of usbhid_open/close
Date: Wed, 31 May 2017 13:59:45 -0700 [thread overview]
Message-ID: <20170531205951.30852-2-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20170531205951.30852-1-dmitry.torokhov@gmail.com>
Instead of calling into usbhid code directly, let's use the standard
accessors for the transport HID drivers.
This also allows us make usbhid_open and close static.
