From: Ioana Ciornei Date: Tue, 28 May 2019 17:38:14 +0000 (+0300) Subject: net: phylink: Add phylink_{printk, err, warn, info, dbg} macros X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=17091180b1521ee9b4455d75ab61b35bc0b216ff;p=openwrt%2Fstaging%2Fblogic.git net: phylink: Add phylink_{printk, err, warn, info, dbg} macros With the latest addition to the PHYLINK infrastructure, we are faced with a decision on when to print necessary info using the struct net_device and when with the struct device. Add a series of macros that encapsulate this decision and replace all uses of netdev_err&co with phylink_err.
