Hello,

I am sending this series because I want to get feedback.

please don't expect it to be perfect (yet). especially since it's

touching parts of the kernel I've not worked with before.

my goal was NOT to use the user-space initialization tool for the

Bluetooth part of one of my devices (which uses a Realtek RTL8723BS).

my hope was that I only had to hook up serdev support to hci_h5 and

re-use the setup function provided by btrtl. unfortunately it wasn't

that easy.
