net: cpmac: dynamic debug fixes
This patch does the following changes 1. convert printk(KERN_DEBUG.. to netdev_dbg() if we have net_device object or convert to dev_dbg() if we have device object. 2. convert printk(KERN_WARNING.. to netdev_warn() if we have net_device object or convert to dev_warn() if we have device object 3. convert printk() to pr_* Signed-off-by: Varka Bhadram <varkab@cdac.in> Signed-off-by: David S.
