[libcamera-devel] [PATCH v2 01/30] cam: options: Make KeyValueParser::usage() private

[Laurent Pinchart]

The KeyValueParser::usage() function is meant to be called from an
OptionsParser or another KeyValueParser only. Make it private, and set
the OptionsParser class as a friend of the KeyValueParser class.
