Follow-ups
--- Cliff Cai 2010-01-21 02:22:40
Since DMA irq no longer gets IRQF_DISABLED when requested,now need to consider
interrupt nest problem.During DMA tx interrupt handler waiting for sport to
complete transfer,sport underflow problem can happen,the error interrupt handler
needs to return quickly in this situation.

introduce a new way to fix this bug,just disable unwanted error interrupt when
waiting for sport tx transfer to finish.
