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.

--- Cliff Cai                                                2010-01-25 01:23:36

introduce a new way to fix this bug,just disable unwanted error interrupt when

waiting for sport tx transfer to finish.

Yes,fixed. Close.
