      Input: sur40 - skip all blobs that are not touches · 4323418d
      Florian Echtler authored
      The SUR40 labels all reported blobs as touch, token, or generic blob.
      Previously, all blobs were reported as touch regardless of type, causing
      lots of false positives. Present patch fixes this.

      Input: sur40 - silence unnecessary noisy debug output · 335abaea
      Florian Echtler authored
      This information is unneccessary, even as debug output.
      Leave commented out as documentation of the packet ID quirk.

      Input: sur40 - add additional reverse-engineered information · 435915ea
      Florian Echtler authored
      Due to recent reverse engineering efforts, a lot more information is now
      available about the internals of the SUR40. We document this in the kernel
      driver for future use.

      Input: i8042 - fix crash at boot time · 340d394a
      Chen Hong authored
      The driver checks port->exists twice in i8042_interrupt(), first when
      trying to assign temporary "serio" variable, and second time when deciding
      whether it should call serio_interrupt(). The value of port->exists may
      change between the 2 checks, and we may end up calling serio_interrupt()
      with a NULL pointer:

      To avoid the issue let's change the second check to test whether serio is
      NULL or not.
      
      Also, let's take i8042_lock in i8042_start() and i8042_stop() instead of
      trying to be overly smart and using memory barriers.
