Bastien,

The subject of this patch needs a bit more detail. I know that you mean the 
RTL8723B versions of the Bluetooth devices. The subject should say this.

The commit message needs a bit more detail. Referencing the E-mail thread is OK, 
but a bit more is needed. What fails without this change?

To help keep that patches straight, change the next submission to say "[PATCH 
V2]" in the subject. In addition, after the ---, add a section saying what 
changed in V2. That info is not retained in the final commit message in the 
repo, but it can be very useful to a maintainer.

And while at it, please use links that include the message-id (e.g.
mid.gmane.org) so it's searchable even if the archive disappears.

while this is most likely a good start to get people going and testing the hardware, I think long-term some these IDs have to move out of this driver and into a Realtek specific UART slave driver (once we get such a thing upstream).

I think one example would be what Fred is currently doing for the Broadcom UART devices. Essentially we are currently misusing the RFKILL switch for an on/off switch of the GPIO lines. This would be better handled by the Bluetooth subsystem itself when you power on the controller.

Regards

Marcel

Duly noted. I'll postpone that until I have time to do hardware
enablement on the Bluetooth side of that chipset.

Nothing yet, as the current Bluetooth support for this device is
completely in user-space, and doesn't sync up with rfkill.

I already submitted this patch? I certainly forgot doing so :)

Didn't know that service, thanks.

BTW, I recently found out that kernel.org has a this type of service as
well. From https://lkml.kernel.org/:

http://lkml.kernel.org/r/<message-id> - for marc.info links
http://lkml.kernel.org/g/<message-id> - for gmane.org links
