For consistency in kernel printk output for devices, use dev_dbg(),
dev_warn(), dev_err() instead of pr_debug(), pr_warning() and
pr_err(), some of which currently use direct access of name from
platform_device and others of which use dev_name().  Using the dev_*
versions uses the standard device naming from the driver core.

Some pr_* prints were not converted with this patch since they are
used before the platform_device and struct device are created so
neither the dev_* prints or dev_name() is valid.

Unless there are objections, I'll queue this as a fix for the v3.1-rc cycle.

I wonder why these have to be warnings, I get quite a lot of them and
find them rather annoying. Or is my hardware broken or something?

I know other people are disabling this in their trees too:

No, your hardware is not broken.

Patches to change that are welcome on the list.  

It's not related to this patch which just changes from pr_warning to
dev_warn, so needs to be done in a separate patch.
