Subject: [PATCH 00/33] leds: cleanup LP5521/5523 LED driver

LP5521, LP5523 and L55231 have common features as below.

 Register access via the I2C.
 Device initialization/de-initialization.
 Create LED class devices for multiple output channels.
 Device attributes for user-space interface.

Therefore, this patch-set removes duplicate code for LP5521/5523 driver and
makes coherent driver structure, named lp55xx.

All patches have been tested in LP5521, LP5523 and LP55231 evaluation boards.

You can also pull from the location below.
This branch is based on 'for-next' branch of linux-leds.

  leds-lp55xx: use lp55xx common deinit function
  leds-lp55xx: use lp55xx common led registration function
  leds-lp55xx: use lp55xx_init_led() common function
  leds-lp55xx: use lp55xx_set_brightness() for brightness control
  leds-lp55xx: provide common LED current setting
  leds-lp55xx: use lp55xx_unregister_leds()
  leds-lp55xx: fix error condition in lp55xx_register_leds()
  leds-lp55xx: add new lp55xx_register_sysfs() for FW interface

Adding the firmware interface
  leds-lp55xx: support firmware interface
  leds-lp55xx: use generic firmware interface

Cleanups lp5521, lp5523 device attributes
  leds-lp55xx: support device specific attibutes
  leds-lp55xx: use common driver function for adding attributes

Others
  leds-lp55xx: code refactoring on selftest function
  leds-lp55xx: add unregister dev attr function
  leds-lp55xx: clean up _remove()
  leds-lp55xx: clean up unused data and functions
  leds-lp55xx: clean up definitions
  leds-lp55xx: clean up headers
  leds-lp5521: recovers previous driver patch for return value
  leds-lp5521/5523: use new lp55xx common header
