3.16.7-ckt26 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Luis Henriques <luis.henriques@xxxxxxxxxxxxx>
This reverts commit 0f7b4f7914e450b1bcffdbd26bbf35ee304cbfea, which was
commit ff4319dc7cd58c92b389960e375038335d157a60 upstream.
This commit introduced a regression in this kernel. Commit 95be58df74a5
("firmware: dmi_scan: Use full dmi version for SMBIOS3") added support for
SMBIOS3. However, this was not backport to this kernel version, and thus
commit ff4319dc7cd5 should have not been applied.
