Hmm, it should. In synaptics.c:
#if defined(CONFIG_MOUSE_PS2_SYNAPTICS) || \
defined(CONFIG_MOUSE_PS2_SYNAPTICS_SMBUS)
int synaptics_init(struct psmouse *psmouse)
{
struct synaptics_device_info info;
int error;
int retval;
psmouse_reset(psmouse);
...
}
The intent was to allow disabling the PS/2 portion of Synaptics driver
while retaining the switching to SMbus capability.
Thanks.
