The component requires the compare/release functions, there are many copies in current kernel. This patchset just defines four common helpers for them. No functional change. Change note: v1: a) Split the original patch into many small patches. b) Use device_match_of_node helper. c) Move the functions into c and export since the callback doesn't look like it should be "inline". d) Add "component_" prefix for the functon names. e) Add a new component_compare_dev_name.
