From eded9dd40b1e30215ab7379dc433f3d3c662ec88 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 14 Aug 2013 15:27:08 -0600 Subject: of: move documentation of of_parse_phandle_with_args Commit bd69f73 "of: Create function for counting number of phandles in a property" renamed of_parse_phandle_with_args(), and created a wrapper function that implemented the original name. However, the documentation of the original function was not moved, leaving it apparently documenting the newly renamed function. Move the documentation so that it is adjacent to the function it documents.
