Yes. It's built-in in my Samsung labtop bought on market.

It works well. I test basic things such as searching, sdp, and pairing.
and they works fine.

Actually before I use your driver/firmware, my "hciconfig -a" shows
wrong address and hci 4.0. but thanks to your driver/firmware I could
get hci 4.1 and normal address.

No. I just use fedora 22, 4.0.3-300.fc22.x86_64. In case of wifi they
use PCI, so it's not easy to use it in guest os that use latest kernel
tree.

Also I search some mail thread for ath10k, it seems that firmware is
not added in linux-firmware until now.

I appreciate your help a lot. I could use my Bluetooth on my labtop
from now on.
