The patch titled Subject: backlight: tdo24m: use devm_ functions has been removed from the -mm tree. Its filename was backlight-tdo24m-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: Jingoo Han <jg1.han@xxxxxxxxxxx> Subject: backlight: tdo24m: use devm_ functions The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc of these functions.
