Subject: [PATCH 08/16] perf ui/gtk: Reuse generic __hpp__fmt() code
From: Namhyung Kim <namhyung@...nel.org>
The __hpp__color_fmt used in the gtk code can be replace by the generic
code with small change in print_fn callback.
This is a preparation to upcoming changes and no functional changes
intended.
