From eb2897b113a04229c7749d1c23990c984775ca13 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 24 Jul 2023 18:37:51 -0500 Subject: [PATCH] mb/samsung/lumpy: 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.
