5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonathan Denose <jdenose@xxxxxxxxxx>

[ Upstream commit da897484557b34a54fabb81f6c223c19a69e546d ]

The kernel reports that the touchpad for this device can support a
different bus.

With SMBus enabled the touchpad movement is smoother and three-finger
gestures are recognized.
