From a6076cfcfdbe46e81e598e4761eb5d4c4a4082ab Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 24 Jul 2023 18:33:46 -0500 Subject: mb/google/butterfly: override SMBus subsystem ID Necessary to allow coolstar's Windows touchpad driver for this board, since the touchpad is attached to the SMBus. The VID/DID combo used is not registered/doesn't conflict with any currently in use, and would be difficult to change at this point since the Windows drivers have already been signed. TEST=build/boot Win11, Linux on butterfly/lumpy/parrot, verify touchpad driver works properly.
