staging: unisys: Process more than one response per check (7c03621a) · Commits · 戴 / test

When s-Par is in polling mode it checks every 2 ms to see if there is a response from the IO service partition in the queue. Currently it just reads one entry per 2 ms, this needs to be changed so it drains the queue on each check. Signed-off-by:
