Subject: [PATCH] DMI to disable Vista compatibility on MSI GX723 Notebook

The brightness control hotkey don't work with Vista compatibility
, because MSI GX723 included a infinite while loop in DSDT when
brightness control hotkey pressed.
MSI GX723 used Nvida video card, the infinite while loop must be a
workaround with Nvidia's Vista driver.
