    rsi: Use resume_noirq for SDIO · c434e5e4
    Marek Vasut 提交于
    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.
    
    Fixes: 20db0733 ("rsi: sdio suspend and resume support")
