[PATCH 6/6] dmaengine: tegra-apb: Disable interrupts on removal

From: Jon Hunter
Date: Fri Oct 16 2015 - 04:26:27 EST


On driver removal, before killing any tasklets, ensure that the channel
interrupts are disabled so that the tasklet will not try to run during
or after the removal of the driver.
