cam: options: optional arguments needs to be specified as --foo=bar
It's not stated in the getopt_long documentation but optional arguments need to be specified as '--foo=bar' instead of '--foo bar', otherwise the value is not propagated to optarg during argument parsing. Update the usage printing helper to reflect this requirement. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
