4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@xxxxxxxx>
[ Upstream commit b004b21cc664ca00782508514dade43e29eebf94 ]
Sergey reported that some much older Dell systems don't support
the OEM string "Dell System" but instead supported www.dell.com
in OEM strings.
Match both of these to indicate that this driver is running on
a Dell system.
