[PATCH 2/4] patman: Refactor MakeCcFile() into two functions

Simon Glass sjg at chromium.org
Sun Feb 19 17:31:21 CET 2023


This function is quite long. Moving the handling of a commit into a
separate function. This will make it easier to do the work in parallel.

Update function comments while we are here.
