dmesg outpur with kernel 4.16.5 and fix
Hi Takashi,
I tested provided kernel and would like to say that fix seems to be
non-working, BT is dead. After boot I found in dmesg about ath3k:
ivan@mynote:~> dmesg | grep ath3
[ 6.655436] ath3k: probe of 1-10:1.0 failed with error -2
[ 6.655460] usbcore: registered new interface driver ath3k
Hope this "error -2" will put some light here.
