carma-fpga: fix lockdep warning Lockdep occasionally complains with the message: INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected This is caused by calling videobuf_dma_unmap() under spin_lock_irq(). To fix the warning, we drop the lock before unmapping and freeing the buffer. Signed-off-by: Ira W.
