[PATCH v1] scsi: Improve style of pnp_device_id array terminator

[Uwe Kleine-König (The Capable Hub)]

To match how device-id array terminators look like for other device
types drop `.id = ""` from it and let the compiler care for zeroing the
entry.

There are no changes in the compiled drivers, only the source looks
nicer.

Hello,

I'm currently working on changing various *_device_id definitions.
This patch is irrelevant for this quest and a pure style update for
consistency reasons without further dependencies on it. I just stumbled
over this while working on that quest.

So if you don't like this patch, I won't insist.

Best regards
Uwe

It seems to be standard practice to use { .id = "" } as pnp dev table 
sentinel - so why change? Are they all going to be changed?

I sent several patches reworking pnp_device_id arrays. Both styles exist
(and also { "", 0 }) and I adapted all arrays I touched to the { } style
matching what is usual for all other *_device_id arrays I saw so far.

And I sent this patch only to create consistency. I think I catched most
instances already, and before declaring the quest done I will make sure
to tackle also those that I now might have missed for now.

Best regards
Uwe

Although in general I'm not a fan of code cleanups for legacy drivers, I
like this change. Hence:

Applied to 7.3/scsi-staging, thanks!
