-Subject: [PATCH] virt: vbox: Fix guest capabilities mask check
-
-Check the passed in capabilities against VMMDEV_GUEST_CAPABILITIES_MASK
-instead of against VMMDEV_EVENT_VALID_EVENT_MASK.
-This tightens the allowed mask from 0x7ff to 0x7.

-Fixes: 0ba002bc4393 ("virt: Add vboxguest driver for Virtual Box Guest integration")
