Subject: [PATCH v2 0/6] leds: netdev trigger: allow setting initial values in device tree

Here's a reroll of the attempt to allow initializing led_netdev_data
from DT, fixing minor bugs and inconsistensies I found while digging
into the code.

Changes in v2:

* use 0 instead of '\0' for consistency with existing code [Pavel]
* name the helper netdev_trig_set_device [Uwe]
* add a patch allowing echoing 15-character names to device_name 
* ensure the length checking is done in one place [Uwe]
* drop hunk from CAN Kconfig file for now [Uwe]
* don't mention CONFIG_CAN_LEDS in device tree binding [Uwe]
* guard netdev_trig_of_init by LED_INIT_DEFAULT_TRIGGER bit [Jacek]

Rasmus Villemoes (6):
  leds: netdev trigger: use memcpy in device_name_store
  leds: netdev trigger: factor out middle part of device_name_store
  leds: netdev trigger: move newline handling back to device_name_store
  leds: netdev trigger: move name length checking to
    netdev_trig_set_device
  leds: netdev trigger: add documentation to leds/common.txt
  leds: netdev trigger: allow setting initial values in device tree
