Hi,

even though I like the idea of convention-over-code, but if that's
changing allowed LED names that would risk breaking things, eg:

a) existing DT's (in the field) become incompatible with newer
   kernel versions
b) existing userlands that rely on speicific LED names become
   incomatible with newer kernel versions.
