When the original mac addresses are not valid assign the first one to the internal wifi core, this matches the manufacture mac address in most cases. In addition refresh the patches. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 41545

broadcom-wl driver bound to ssb device with ssb driver probe
|
|
have osh handle struct pdev pointer value initialized with
|
|
ssb_device pointer. Later on pdev is used with legacy pci
|
|
dma api as pci_dev thus causing oops sometimes.
|
|
|
|
The patch replaces legacy pci dma api and pass relevant
|
|
device struct pointer to avoid crashes.
