Raw Blame History

From d00a8281bcc962027dfe409c2f3e3f0546be9200 Mon Sep 17 00:00:00 2001

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