The following contains a clarification for the behavior of the 'value' parameter in the memset operation. It is intended to be a single byte pattern as laid out here: https://lore.kernel.org/dmaengine/YejrA5ZWZ3lTRO%2F1@matsya/ Then I'm attempting to fix all places it is currently used. But note that I do not have access to this hardware and cannot test it. We'll really need a maintainer to take a look at each of these to verify that the changes are correct.
