Subject: [PATCH RESEND 9/9] mtd: mtd_oobtest: printk -> pr_{info,err,crit}
Date: Wed, 10 Oct 2012 23:12:02 +0530 [thread overview]
Message-ID: <5075B36A.3050009@gmail.com> (raw)
In-Reply-To: <5075B105.4080701@gmail.com>
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).
