This patch series primarily deals with a potential UAF inside
the dell-smbios-wmi driver reported by a user. The first patch
fixes this issue, with the remaining two patches further
cleaning up the resource management.

All patches have been tested on a Dell Inspiron 3505 and appear
to work. I also verified that the UAF issue does not occur anymore
after applying the first patch.
