      Input: alps - non interleaved V2 dualpoint has separate stick button bits · 92bac83d

      Non interleaved V2 dualpoint touchpad / stick combos have separate stick
      button bits in the touchpad packets, if we do not check these then the
      trackpoint buttons will not work when using the touchpad, and when pressed
      when the user starts using the touchpad will report a release event even
      though the button is still pressed.
      
      This commit fixes this by checking the separate bits, note that we simply
      combine the buttons, since the hardware does the same when using the touchpad
      buttons with the trackpoint, so we do not have enough information to properly
      separate them.

      Input: alps - fix touchpad buttons getting stuck when used with trackpoint · 6bcca19f
      Hans de Goede authored
      When the left touchpad button gets pressed, and then the trackpoint is
      moved, and then the button is released, the following happens:
      
      1) touchpad packet is received, touchpad evdev node reports BTN_LEFT 1
      
      2) pointing stick packet is received, the hw will report a BTN_LEFT 1 in
         this packet because when the trackstick is active it communicates the
         combined touchpad + pointing stick buttons in the trackstick packet,
         since alps_report_bare_ps2_packet passes NULL (*) for the dev2 parameter
         to alps_report_buttons the combining is not detected and the
         pointing stick evdev node will also report BTN_LEFT 1
      
      3) on release of the button a pointing stick packet with BTN_LEFT 0 is
         received and the pointing stick evdev node will report BTN_LEFT 0
      
      Note how because of the passing as NULL for dev2 the touchpad evdev node
      will never send BTN_LEFT 0 in this scenario leading to a stuck mouse button.
      
      This is a regression in 4.0 introduced by commit 04aae283
      ("Input: ALPS - do not mix trackstick and external PS/2 mouse data")
      
      This commit fixes this by passing in the touchpad evdev as dev2 parameter
      when calling alps_report_buttons for the pointingstick on alps v2 devices,
      so that alps_report_buttons correctly detect that we're already reporting
      the button as pressed via the touchpad evdev node, and will also send the
      release event there.
