@Igor Don't get me wrong, but are you sure it's not otherwise?
After updating my A20-Lime from Armbian 5.25 (mainline) to latest stable version (5.35) through `apt upgrade`, I got precisely the same error as the OP with kernel 4.13.16.
If I'm reading well, the problem described in the OP is precisely with mainline kernel @ version 5.35, stating the legacy kernel @ version 5.35 works just fine.
Checking your patch @ git, are sure you shouldn't apply that patch also to A20-Lime? You seem to have forgotten that board...
