Running:
    scripts/checkpatch.pl -f arch/arm/mach-s3c24xx/mach-mini2440.c
revealed several errors and warnings.

They were all removed, except one which is an #if 0 around the declaration
of a gpio pin. This needs some more investigation and I prefer to let it
here. This is not some dead code.

'printk' was replaced by 'pr_info'.

Thanks, applied.

Best regards,

pr_cont

So only the first printk should use pr_info().
The subsequent printk uses should use pr_cont()

at this point, I don't know what to do.

Should I resubmit the patches? Or is it in the hands of
Krzysztof (krzk@kernel.org)? I would say a git rebase -i
is enough to edit the patch and this rebase is obviously
not to be done by me, but I don't know the process.

Regards,
Cédric.

Can you send a incremental fix for this, restoring the original
continued printks?
