Race condition exists between the cppi_interrupt handler and davinci_interrupt handler w.r.t completing a TX IO. Since DM646x has seperate DMA and USB Endpoint interrupts cppi_interrupt handler needs to hold the lock while operating on the endpoint. Signed-off-by: Swaminathan S <swami.iyer@xxxxxx>
NAK. davinci_interrupt() calls cppi_interrupt() with this lock already held. We probably need to move the lock acquisition below that call first.
