From a0ac6d8e17587dea87091aee13abd47d1777e035 Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Wed, 15 Jan 2014 16:56:08 +1100 Subject: [PATCH] drivers/video/backlight/lcd.c: call put_device if device_register fails Currently we kfree the container of the device which failed to register. This is wrong as the last reference is not given up with a put_device call. Also, now that we have put_device() callen, we no longer need the kfree as the new_ld->dev.release function will take care of kfreeing the associated memory.
