   4 Subject: [PATCH 1/5] net: ethernet: bgmac: change bgmac_* prints to dev_*
   5  prints
   6
   7 The bgmac_* print wrappers call dev_* prints with the dev pointer from
   8 the bcma core.  In anticipation of removing the bcma requirement for
   9 this driver, these must be changed to not reference that struct.  So,
  10 simply change all of the bgmac_* prints to their dev_* counterparts.  In
  11 some cases netdev_* prints are more appropriate, so change those as
  12 well.
