Input: alps - report pressure of v3 and v7 trackstick
ALPS v3 and v7 packet formats reports trackstick pressure. This information is already parsed in unused "z" variable. ALPS SS4 S2 devices already reports trackstick pressure as ABS_PRESSURE attribute, therefore reports pressure in the same way also for v3 and v7. This patch also updates parsing v3 pressure information, it is also stored in 7 bits. Signed-off-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
