dmaengine: mv_xor_v2: kill the tasklets upon exit
[ Upstream commit 8bbafed8dd5cfa81071b50ead5cb60367fdef3a9 ]
The mv_xor_v2 driver uses a tasklet, initialized during the probe()
routine. However, it forgets to cleanup the tasklet using
tasklet_kill() function during the remove() routine, which this patch
fixes. This prevents the tasklet from potentially running after the
module has been removed.
