Input: psmouse - reset all types of mice before reconnecting
commit ef110b24e28f36620f63dab94708a17c7e267358 upstream.
Synaptics hardware requires resetting device after suspend to ram
in order for the device to be operational. The reset lives in
synaptics-specific reconnect handler, but it is not being invoked
if synaptics support is disabled and the device is handled as a
standard PS/2 device (bare or IntelliMouse protocol).
Let's add reset into generic reconnect handler as well.
