From: Heiner Kallweit <hkallweit1@xxxxxxxxx> commit d182bcf300772d8b2e5f43e47fa0ebda2b767cc4 upstream. The usage of edge-triggered interrupts lead to lost interrupts under load, see [0]. This was confirmed to be fixed by using level-triggered interrupts. The report was about SDIO. However, as the host controller is the same for SD and MMC, apply the change to all mmc controller instances.
