2012-09-24brcmfmac: clear status for in-band interrupt in brcmf_sdbrcm_isrFranky Lin
SDIO in-band interrupt is level sensitive according to SDIO standard. When the register interrupt handler gets called by SDIO stack it is running in non interrupt context and expected to clear the interrupt from the dongle. Therefore in-band and out-of-band interrupt need to be handled differently.

2012-09-24brcmfmac: raise SDIO host lock to higher levelFranky Lin
Use SDIO host lock to protect the entire communication process of register access or data read/write rather than function calls to MMC/SDIO stack only. This can help to avoid unintentional memory access and unexpected interruption.
