+Subject: [PATCH] quirks: Add Apple MTP touchpad quirk
+
+Apple M2 (and presumably newer) laptops now embed the touchpad
+controller into the main SoC, and use a new internal communications
+protocol between it and the main CPU. This isn't really a "bus" like
+SPI or I2C, so the downstream kernel driver currently uses the (not
+well supported) HOST bus type. MatchBus can't match on that, so let's
+just use a name match (plus the vendor ID, which is still valid and
+the usual Apple one).
