-Subject: [PATCH 2/3] net: bgmac: drop struct bcma_mdio we don't need anymore
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Adding struct bcma_mdio was a workaround for bcma code not having access
-to the struct bgmac used in the core code. Now we don't duplicate this
-struct we can just use it internally in bcma code.
-
-This simplifies code & allows access to all bgmac driver details from
-all places in bcma code.
