All of these patches are cleanups, and as such as not appropriate for

I think these are al relatively poor cleanups as
it is now no longer visually obvious that these
MBP_<FOO> defines are related to CPMAC_MBP

If you really want to do this I suggest something like:
#define CPMAC_MBP			0x0100
#define		MBP_RXPASSCRC		0x40000000

[PATCH net 3/7] net: cpmac: dynamic debug fixes

[varkabhadram]

From: Varka Bhadram <varkab@cdac.in>

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_*
