From: Bjorn Helgaas Date: Mon, 28 Apr 2014 21:16:33 +0000 (-0600) Subject: x86/gart: Replace printk() with pr_info() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a5d3244a0b1c16963fd7ceadf76da843df27c3c5;p=openwrt%2Fstaging%2Fblogic.git x86/gart: Replace printk() with pr_info() Replace printk() with pr_info(), pr_err(), etc. Define pr_fmt() to prefix output with "AGP: ". No functional change except the addition of "AGP: " prefix in dmesg output.
