[PATCH 5.7 164/393] cxl: Fix kobject memleak

From: Greg Kroah-Hartman
Date: Mon Aug 17 2020 - 14:59:52 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")
