[PATCH v3 0/2] platform/x86: Fix reference leaks

[Armin Wolf]

If a duplicate attribute is found using kset_find_obj(), a reference
to that attribute is returned which needs to be disposed accordingly
using kobject_put(). This issue likely first appeared inside the
dell-wmi-sysman driver, see
commit 7295a996fdab ("platform/x86: dell-sysman: Fix reference leak").
However, it also seems that the bug was copied from this driver into
the think-lmi and hp-bioscfg drivers. Maybe a more abstract
fw_attr_class could prevent such issues in the future by abstracting
away the kobject handling?
