Subject: [PATCH] media: atomisp: add Asus Transform T101HA ACPI vars

Those were extracted from an ACPI dump:

 * Original Table Header:
 *     Signature        "DSDT"
 *     Length           0x0001A0BD (106685)
 *     Revision         0x02
 *     Checksum         0x76
 *     OEM ID           "_ASUS_"
 *     OEM Table ID     "Notebook"
 *     OEM Revision     0x01072009 (17244169)

                            "0"
                        }

Note: the DMI_MATCH() line probably needs to be tweaked.
