Does checkpatch complain about this, really? This is a code change and
needs to be explained in the commit message at least.

This is ugly. Do:
brd = kzalloc(sizeof(struct board_t), GFP_KERNEL);
if (!brd)
return -ENOMEM;
dgap_Board[dgap_NumBoards] = brd;
Except really that assignment should happen after the other allocations
which can fail. Otherwise we end up with a freed pointer in
dgap_Board[dgap_NumBoards] on error.

Double negatives hurt your brain cells for no reason. (This has been
proven by science).
