From a6ddd2f1b99f1c00b4e00289b13c3e451c7130b0 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Wed, 17 Feb 2016 17:43:27 +0530 Subject: [PATCH] drm/udl: Use module_usb_driver Macro module_usb_driver is used for drivers whose init and exit paths only register and unregister to usb API. So remove boilerplate code to make code simpler by using module_usb_driver. This change was made with the help of the following Coccinelle semantic patch: // @a@ identifier f, x; @@ -static f(...) { return usb_register(&x); } @b depends on a@ identifier e, a.x; @@ -static e(...) { usb_deregister(&x); } @c depends on a && b@ identifier a.f; declarer name module_init; @@ -module_init(f); @d depends on a && b && c@ identifier b.e, a.x; declarer name module_exit; declarer name module_usb_driver; @@ -module_exit(e); +module_usb_driver(x); // Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20160217121327.GA29682@amitoj-Inspiron-3542 --- drivers/gpu/drm/udl/udl_drv.c | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-) diff --git a/drivers/gpu/drm/udl/udl_drv.c b/drivers/gpu/drm/udl/udl_drv.c index d5728ec85254..772ec9e1f590 100644 --- a/drivers/gpu/drm/udl/udl_drv.c +++ b/drivers/gpu/drm/udl/udl_drv.c @@ -125,17 +125,5 @@ static struct usb_driver udl_driver = { .disconnect = udl_usb_disconnect, .id_table = id_table, }; - -static int __init udl_init(void) -{ - return usb_register(&udl_driver); -} - -static void __exit udl_exit(void) -{ - usb_deregister(&udl_driver); -} - -module_init(udl_init); -module_exit(udl_exit); +module_usb_driver(udl_driver); MODULE_LICENSE("GPL"); -- 2.20.1
