Pull LED fixes from Jacek Anaszewski:
 "All three fixes are related to the newly added pattern trigger:

   - remove mutex_lock() from timer callback, which would trigger
     problems related to sleeping in atomic context, the removal is
     harmless since mutex protection turned out to be redundant in this
     case

   - fix pattern parsing to properly handle intervals with brightness == 0

   - fix typos in the ABI documentation"
