2014-01-06brcmfmac: enable watchdog when bus initialization is completeArend van Spriel
Change condition in brcmf_sdio_wd_timer() function to program watchdog only when in BRCMF_BUS_DATA state. This avoids watchdog being active during initialization. During initialization the SDIO save&restore capability is determined which affect the bus sleep mechanism used in watchdog thread.
