Pali Rohár 9096a45d99 Input: psmouse - use same format for secondary devices as for primary
This patch changes name of secondary psmouse devices to mach format of
primary device. Format of primary device is "protocol vendor name" and is
set by function psmouse_switch_protocol() in file psmouse-base.c.
