Matthew R. Ochs 6f81dea403 scsi: cxlflash: Improve EEH recovery time ... commit 05dab43230fdc0d14ca885b473a2740fe017ecb1 upstream. When an EEH occurs during device initialization, the port timeout logic can cause excessive delays as MMIO reads will fail. Depending on where they are experienced, these delays can lead to a prolonged reset, causing an unnecessary triggering of other timeout logic in the SCSI stack or user applications. To expedite recovery, the port timeout logic is updated to decay the timeout at a much faster rate when in the presence of a likely EEH frozen event. Signed-off-by: Matthew R.
