This is a pure rename without any changes. It makes maintaining bgmac simpler and will hopefully make adding new kernel a bit easier. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH 2/5] net: ethernet: bgmac: add dma_dev pointer
|
|
|
|
The dma buffer allocation, etc references a dma_dev device pointer from
|
|
the bcma core. In anticipation of removing the bcma requirement for
|
|
this driver, these must be changed to not reference that struct. Add a
|
|
dma_dev device pointer to the bgmac stuct and reference that instead.
