Actually my suggestion was to make this a two-patch series: 1/2 debugcon: Fix debug format specifiers 2/2 debugcon: Separate debug console output from device debug output The former would do both HWADDR_PRIx and PRIx64 in one go and not do a lengthy example or "Oh, that's wrong" in the commit message. The latter would change where/how the debug output is written, without changing to " [...]". Thinking more about this, I think it would be best to turn this into a DPRINTF() macro or so, then the change can be made in one central location and the inline #ifdefs can be dropped. Bonus points if the macro were designed in such a way that even if DEBUG_DEBUGCON is not defined the (f)printfs get tested, to avoid regressions. :) Regards, Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
