In commit 9d9491a7da2a ("mmc: dw_mmc: Fix the DTO timeout calculation") have been made changes which cause multiply overflow for 32-bit systems. The broken timeout calculations caused false interrupt latency warnings and stacktrace splat (such as below) when accessing the SD Card.

•   drto_ms = DIV_ROUND_UP((u64)MSEC_PER_SEC * drto_clks * drto_div,
                           host->bus_hz);
  

Same as per patch 2.
