Subject: [PATCH] backlight: replace kfree with put_device
Date: Fri, 7 Feb 2014 09:43:21 +0100 [thread overview]
Message-ID: <1391762601-4560-1-git-send-email-levex@linux.com> (raw)
As per the comments on device_register, we shouldn't call kfree()
right after a device_register() failure. Instead call put_device(),
which in turn will call bl_device_release resulting in a kfree to the
full structure.
