[PATCH leds v2 00/50] Start moving parsing of `linux,default-trigger` to LED core (a cleanup of LED drivers)

["Marek Behún" <marek.behun@nic.cz>]

Hi,

this series is also available at [1].

This is v2, you can read cover letter of v1 at [2] (togehter with
explanation of why I did this).

Changes since v1:
- split big changes into several patches of little changes
- added many cosmetic fixes (helper variables, reversal christmas tree
  variables declaration, ...)
- fixed some bugs in various drivers (memory leaks, iteration over
  unavailable OF nodes)
- made some drivers compilable when COMPILE_TEST=y (since allyesconfig
  did not compile them). Not all though, some still don't compile with
  allyesconfig
- the commit that moves parsing of `linux,default-trigger` property from
  drivers to LED core is now last in the series, instead of first

Marek
