Subject: [1/2] EDAC: fix memleak in module init error path
Date: Tue, 12 Jun 2018 14:43:34 +0200 [thread overview]
Message-ID: <20180612124335.6420-1-johan@kernel.org> (raw)
Make sure to use put_device() to free the initialised struct device so
that resources managed by driver core also gets released in the event of
a registration failure.
Fixes: de3910eb79ac ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy")
Fixes: 2d56b109e3a5 ("EDAC: Handle error path in edac_mc_sysfs_init() properly")
