rpm/0051-Extract-package-file-list-processing-in-separate-fun.patch

From bc5990647ad94fcb4acdb68612e16fe514ee59b7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 51/54] Extract package file list processing in separate
 functions.

Extract two functions resetPackageFilesDefaults() and addPackageFileList()
from processPackageFiles(). This will make it possible to add multiple
(generated) file lists to a package later.

(cherry picked from commit 139d62d3b8068b0e39893babf13f0c3cc5329e75)
