[PATCH 00/24] Convert serio-related drivers to use new cleanup facilities

[Dmitry Torokhov]

Hi,

This series converts drivers found in drivers/input/serio as well as a
few of input drivers using serio to use new __free() and guard() cleanup
facilities that simplify the code and ensure that all resources are
released appropriately.

First patch introduces serio_pause_rx guard that pauses delivery of
interrupts/data for a given serio port by calling serio_pause_rx()
helper and automatically resumes it by calling serio_resume_rx() when
needed.

The following 8 patches make use if this new guard.

The rest of the patches switch serio drivers to use guard(mutex),
guard(spinlock*) and other cleanup functions to simplify the code.

Thanks!

Dmitry Torokhov (24):
  Input: serio - define serio_pause_rx guard to pause and resume serio ports
  Input: libps2 - use guard notation when temporarily pausing serio ports
  Input: alps - use guard notation when pausing serio port

  Input: synaptics-rmi4 - use guard notation when pausing serio port in F03
  Input: elo - use guard notation when pausing serio port
  Input: gscps2 - use guard notation when acquiring spinlock
  Input: hyperv-keyboard - use guard notation when acquiring spinlock
  Input: i8042 - tease apart interrupt handler
  Input: i8042 - use guard notation when acquiring spinlock
  Input: ps2-gpio - use guard notation when acquiring mutex
