I don't see why you include the .h and .h.orig files into the patch dir. The changes are in the .patch files
so only those files are relevant.

The issue is in your patch files. 

--- psplash-config.h.orig       2025-09-03 15:01:21.282531766 -0400
+++ psplash-config.h    2025-09-03 15:10:18.445116066 -0400

should be

--- psplash-config.h       2025-09-03 15:01:21.282531766 -0400
+++ psplash-config.h    2025-09-03 15:10:18.445116066 -0400

I assume you created this diff manually between the two files and not from a git commit.
For the patching we want to apply the change to one file and not to another so the
two lines need to be identical.
