Thanks, I removed obsolete trees.
Shall I ask two more questions;
Did stick plug work now without no_reconnect or any other modifications 
(probably yes)?
How about lock LED? I tried to look sniffs but did not see straight 
answer why it did not work for you. Anyhow, I did small change that 
could affect it.
If you want to play it you can try to change line from frontend/af9013.c
return af9013_write_reg_bits(state, 0xd730, 0, 1, onoff);
to
return af9013_write_reg_bits(state, 0xd730, 1, 1, onoff);
or 2 or 3 to see if it helps.

regards
Antti
