[PATCH v2] mmc: dw_mmc: Fix the DTO timeout overflow calculation for 32-bit systems

2018-02-22 Thread Evgeniy Didin
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. | Running : 4M
