The patch titled Subject: drivers/video/backlight/wm831x_bl.c: use devm_ functions has been removed from the -mm tree. Its filename was drivers-video-backlight-wm831x_blc-use-devm_-functions.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Julia Lawall <Julia.Lawall@xxxxxxx> Subject: drivers/video/backlight/wm831x_bl.c: use devm_ functions The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function.
