Subject: [PATCH v3 0/3] new driver for Valve Steam Controller

This patchset implements a driver for Valve Steam Controller, based on a
reverse analysis by myself.

This is reroll v3, codenamed "lazy lizard". Changes from v2:
 * Use RCU to do the dynamic connec/disconnect of wireless devices. Please,
   to anybody that knows their way around RCU, review.
 * Remove entries in hid-quirks.c as they are no longer needed. This allows
   this module to be blacklisted without side effects.
 * Do not bypass the virtual keyboard/mouse HID devices to avoid breaking
   existing use cases (lizard mode). A user-space tool to do that is
   linked.
 * Fully separated axes for joystick and left-pad. As it happens, there are
   people with too many fingers.
 * Add fuzz values for left/right pad axes, they are a little wiggly.

Notable changes from patchset v1:
 * Remove references to USB. Now the interesting interfaces are selected by
   looking for the ones with feature reports.
 * Feature reports buffers are allocated with hid_alloc_report_buf().
 * Feature report length is checked, to avoid overflows in case of
   corrupt/malicius USB devices.
 * Resolution added to the ABS axes.
 * A lot of minor cleanups.

Rodrigo Rivas Costa (3):
