-From: George Kashperko <george@znau.edu.ua>
-
-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.
-Signed-off-by: George Kashperko <george@znau.edu.ua>
