From: Andrew Morton Date: Thu, 28 Feb 2013 01:03:16 +0000 (-0800) Subject: fs/proc: clean up printks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87ebdc00eeb474615496d5f10eed46709e25c707;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git fs/proc: clean up printks - use pr_foo() throughout - remove a couple of duplicated KERN_WARNINGs, via WARN(KERN_WARNING "...") - nuke a few warnings which I've never seen happen, ever.
