Subject: [PATCH RESEND 9/9] mtd: mtd_oobtest: printk -> pr_{info,err,crit}
Use pr_info() and pr_err() while defining pr_fmt(). This saves a few
characters, joins a few lines, and makes the code a little more readable
(and grep-able).

Pushed the series to l2-mtd.git, thanks!
You can send the erase helper patch as well. I think you can put this
helper to mtdcore.c. And I think UBI and JFFS2 and may be mtdswap and
other drivers may reuse it - you can take a look.

Thanks Artem. Can you please make Brian Norris as the author for the
last patch? i.e., mtd: mtd_oobtest: printk -> pr_{info,err,crit}
I forgot to post the patch with the original headers. But I've reposted
it a few days back. Sorry about that.

Yeah, Sure. I need to grep into the sources to find the users of it.
I'll post it soon.
Thanks,
Vikram
