Subject: dell-smbios: don't return an SMBIOS buffer from
 dell_smbios_send_request()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An SMBIOS buffer pointer does not need to be returned by
dell_smbios_send_request(), because SMBIOS call results are stored in
the buffer exported by the module.
