[PATCH v1 0/3] thunderbold: A few cleanups

[PATCH v1 0/3] thunderbold: A few cleanups

[Uwe Kleine-König (The Capable Hub)]

Hello,

I'm currently working on a project that includes looking at all device
ID structures from <linux/mod_devicetable.h>. While doing that for
tb_service_id, I spotted these patch opportunities.

These are all non-critical and also my quest doesn't depend on this, so
there is no urge to apply these patches. My suggestion is to apply them
via the thunderbold tree during the next merge window with an ack from
the network guys.

The first patch touches drivers/net and drivers/thunderbold. It could
theretically be split, but then this results in at least 3 commits which
seems excessive to handle three drivers, so I kept it as a single patch.

The third patch is a style change and so is subjective. Drop it, if you
don't like it. Here splitting would be easy, but given that patch #1
already touches the same files, letting these go in together without
splitting seems to be sensible.

Best regards
Uwe

[PATCH v1 1/3] thunderbold: Stop passing matched device ID to .probe()

[Uwe Kleine-König (The Capable Hub)]

No driver makes use of that parameter, so drop it and don't spend the
effort to determine the matching entry.

[PATCH v1 3/3] thunderbold: Drop comma after device id array terminator

[Uwe Kleine-König (The Capable Hub)]

The usual style for other device id arrays doesn't have a comma after
the initializer.
