      wifi: wilc1000: disable SDIO func IRQ before suspend · 5ad8897f
      Alexis Lothoré authored
      Issuing a system suspend command raises the following warning:
      WARNING: CPU: 0 PID: 15 at drivers/mmc/core/sdio.c:1042 mmc_sdio_suspend+0xd4/0x19c

      This warning is due to a check in SDIO core ensuring that interrupts do not
      remain enabled for cards being powered down during suspend. WILC driver
      currently does not set the MMC_PM_KEEP_POWER flag, so disable interrupt
      when entering resume.
