Seems this is because there is no longer a default as there was in the case
statement.
If I add a couple of printk sitting on the commit before "bad" I hit the
default case during bootup (before I startx).
[ 5.030315] ADF: Hit first default, reg_offset = 31
[ 5.030406] ADF: Hit second default, reg_offset = 15
diff and full dmesg attached to show timing/position of output.

Of course had I looked at the code rather than just the diff on fdo cgit I
wouldn't have needed to bother with printks -
const u32 num_tile_mode_states = 32;
const u32 num_secondary_tile_mode_states = 16;

Ugh never mind, I see that the last slot should already be set to 0 :-(
Where's the delete post button :-)

removes stray break
OK I think I've found it now.
There's a stray break in the TONGA bit of the new code.
After a quick search I can't find any others.
