From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> It is waiting udelay(50) x 1024 (= 50ms) for status check in worst case, but it is overkill. And we shouldn't use udelay() for 50us (linux/Documentation/timers/timers-howto.txt) Waiting maximum udelay(5) x 1024 (= 5ms) is very enough for status check. This patch fixes these issue.
