I find it far more likely that patches--in terms of fixing problems with small, targeted changes--derives from the use of the term for fixing holes in cloth by sewing on another piece of cloth.

Everything is about patching up clothes or other things. I was just commenting on the “patch-cable seems to be way younger” remark.
