Break the lines which were more than 80 characters into more lines; replace SPACEs with TABs; correct ident at switch-case; change character encoding from ISO-8859-2 to UTF-8. The order of the functions in led-triggers.c changed in order the similar functions can still be together under titles "Used by LED Class", "LED Trigger Interface" and "Simple LED Tigger Interface" as was grouped before when exported with EXPORT_SYMBOL.
