[PATCH 2/2] Bluetooth: btbcm: Add Synaptics 4384 chip support

[Kaihsin Chung]

Add support for the Synaptics 4384 Bluetooth controller
by adding the corresponding chip IDs.
Verify the change on the VIM3 platform.Verified
that the controller initializes successfully and
that firmware loading and basic Bluetooth operation
work as expected.

Re: [PATCH 2/2] Bluetooth: btbcm: Add Synaptics 4384 chip support

[Paul Menzel]

Dear Kaihsin,


Thank you for your patch. Please remember to version patch iterations. 
This should have been [PATCH v2 …]. `git format-patch -v2 …` would do that.

Please add a blank line between paragraphs.

> Verify the change on the VIM3 platform.Verified

Please add a dot after the dot/period.

What is the VIM3 platform. Maybe extend a little. You could also paste 
the new message.
