Subject: [PATCH] thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDOR

From: Manoj Iyer <manoj.iyer@...onical.com>

In the latest V-series bios DMI_PRODUCT_VERSION does not contain
the string Lenovo or Thinkpad, but is set to the model number, this
causes the thinkpad_acpi module to fail to load. Recognize laptop
as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.
