dmaengine: pch_dma: use tasklet_kill in teardown 2014-03-17T13:04:11+00:00 Vinod Koul vinod.koul@intel.com 2014-03-06T06:54:08+00:00 9068b032d0ff9285314d57a88051fe4111bbe73a As discussed in [1] the tasklet_disable is not a proper function for teardown. We need to ensure irq is disabled, followed by ensuring that don't schedule any more tasklets and then its safe to use tasklet_kill(). Here in pch dma driver we need to use free_irq() before tasklet_kill(). So move up the free_irq() which will ensure that the irq is disabled and also wait till all scheduled interrupts are executed by invoking synchronize_irq().
