brcm80211: smac: eliminate a null pointer dereference in dma.c
Though it's unlikely, di may be null, so we can't dereference di->dma.dmactrlflags until we've checked it. Move this de-reference after the check, and adjust the error message to not require de-referencing di. This is based upon Julia's original patch: <1319846297-2985-2-git-send-email-julia@diku.dk> Reported-by:Julia Lawall <julia@diku.dk> Acked-by:
