Subject: Re: [PATCH] imwc3200: move iwmc3200 SDIO ids to sdio_ids.h

Hi Tomas,

> 1. add intel's sdio vendor id to sdio_ids.h
> 2. move iwmc3200 sdio devices ids to sdio_ids.h

this needs a better commit message since you are touching three
subsystems right now.

Please explain what you are doing. Sounds maybe too obvious, but it is
important that we have clear commit message. Especially when it is
touching more than one subsystem and people have to resolve merge
conflicts.

This should not be part of the commit message.

for readability, please indent the SDIO_DEVICE_ID_INTEL...

Otherwise you easily assume you have two SDIO_DEVICE() statement.

Same here.

While you are touching files all over, what about GPS?
