[PATCH] EDAC: printk cleanup 



This implements the following idea:

On Monday 30 January 2006 19:22, Eric W. Biederman wrote:

> Could we add a edac_printk(dev, );  That is similar to dev_printk but
> prints out an EDAC header and the device on which the error was found?
> Letting the rest of the string be user specified.
>
> For actual control that interface may be to blunt, but at least for people
> looking in the logs it allows all of the errors to be detected and
> harvested.
