From: Joe Perches Date: Wed, 11 Sep 2013 21:25:55 +0000 (-0700) Subject: pktcdvd: add struct pktcdvd_device.name to pr_err logging where possible X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fa63c0ab81f55eb5a016c1bcea04fe39c14afbaa;p=openwrt%2Fstaging%2Fblogic.git pktcdvd: add struct pktcdvd_device.name to pr_err logging where possible Add a new pkt_err macro to prefix the name to the logging output. Convert pr_err where there is a non-null struct pktcdvd_device. Includes improvements from Andy Shevchenko.
