The rsi_resume() does access the bus to enable interrupts on the RSI SDIO WiFi card, however when calling sdio_claim_host() in the resume path, it is possible the bus is already claimed and sdio_claim_host() spins indefinitelly. Enable the SDIO card interrupts in resume_noirq instead to prevent anything else from claiming the SDIO bus first.
