[Johan Hovold]

Please fix up the subject of this patch, which should be different from
patch 2/2 and instead summarise what *this* patch does.

Note that keeping the same 2/2 subject on the cover letter is fine as
2/2 is the primary patch and sort of summarises the series.

This belongs in the next patch.

These are currently not sorted by probably should be to make it easier
to look up and add new entries. This could be done in a third,
preparatory, patch.

And you should probably sort the above as well.

[PATCH v12 2/2] Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC QCA2066

[Tim Jiang]

This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.

no need for "nvme name is" if you keep __func__ as a prefix

Add before qca_soc_data_qca6390 to maintain some order.

Keep the entries sorted by compatible.

Thanks for adding the changelog.

You should also add a sentence or two here that describes what the
series does (e.g. just say "This series adds support for ...").

Also make sure to run scripts/get_maintainer.pl on your series. Looks
like you're still missing some maintainers on CC.

You also did not CC at least on person providing review feedback on
earlier versions.

This is not detailed enough for a changelog, but ok, let's forget about
v2-v9 this time, but remember it for your future submissions.

As I mentioned elsewhere, these Subjects should be distinct and
summarise what each patch does.
