Message-ID: <201212171526.55969.hartleys@visionengravers.com> Date: Mon, 17 Dec 2012 15:26:55 -0700 From: H Hartley Sweeten <hartleys@...ionengravers.com> To: Linux Kernel <linux-kernel@...r.kernel.org> CC: <jkosina@...e.cz>, <hsweeten@...ionengravers.com> Subject: [PATCH 1/3] HID: introduce helper for hid_driver boilerplate Introduce the module_hid_driver macro which is a convenience macro for HID driver modules similar to module_usb_driver. It is intended to be used by drivers with init/exit sections that do nothing but register/unregister the HID driver.
