Looks like it is the commit 71a39b869019c97f48bc85d9a8fabceead217d07

https://git.lede-project.org/?p=source.git;a=commitdiff;h=71a39b869019c97f48bc85d9a8fabceead217d07;hp=2a7f669016f2faa29d64a59252556b96a55d071a

Specifically the change to 10_fix_wifi_mac script.

I tested with a live R7800 running up-to-date r3285-1a52d11d38

* reverting commit 1a39b86901 with "patch -R" fixed MACs
* applying the change for 11-ath10k-caldata still produced ok MAC
* applying the change for 10_fix_wifi_mac caused random MAC

Possibly some sneaky whitespace error, or such.

EDIT:
I found it:
extra TAB char after the backslash on the line with 7500v2
"         r7500v2 |\      "
Deleting that tab fixes MACs
