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.
