--- Patch [1]: [PATCH] Input: synaptics - disable InterTouch on ThinkPad T440p (board id 2722) ---

Input: synaptics - disable InterTouch on ThinkPad T440p (board id 2722)

This commit disables SMBus InterTouch for the Lenovo ThinkPad T440p (PNP ID
LEN0036, board id 2722) by default. This addresses an issue where the SMBus
companion takes too long to appear at boot, causing the touchpad to become
unresponsive.

[Severity: Low]
Since info->board_id is defined as a u32 (unsigned 32-bit integer) in struct
synaptics_device_info, should this format specifier be %u instead of %d to
avoid strict type warnings?
