[PATCH 4.9 116/212] cxl: Fix kobject memleak
From: Greg Kroah-Hartman
Date: Thu Aug 20 2020 - 07:57:09 EST
From: Wang Hai <wanghai38@xxxxxxxxxx>
[ Upstream commit 85c5cbeba8f4fb28e6b9bfb3e467718385f78f76 ]
Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking
the kobject.
Fix it by adding a call to kobject_put() in the error path of
kobject_init_and_add().
Fixes: b087e6190ddc ("cxl: Export optional AFU configuration record in sysfs")
