SubjectRe: [RESEND PATCH 04/10] ide-floppy: cleanup debugging macros
Date
On Thursday 03 January 2008, Borislav Petkov wrote:
> There should be no functional change resulting from this patch.

the patch is fine but the description is a bit inaccurate:

* some debug_log() calls were not using "ide-floppy: " prefix

* a few used printk levels different than KERN_INFO (KERN_NOTICE
and KERN_ERR, which is the default one if no level is given)

please fix the description and move the patch at the beggining of
the patch series
