Subject: ARM: use pr_warn_ratelimited() when migrating IRQs
X-Git-Tag: v3.19-rc1~98^2~1^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=108900b54dce19aab3fa48adde7138ed868bb109;p=platform%2Fkernel%2Flinux-exynos.git

ARM: use pr_warn_ratelimited() when migrating IRQs

Rather than open coding the printk_ratelimit() check with pr_warn(), use
pr_warn_ratelimited() instead.
