Dan Williams f6ab95b557 ioat: preserve chanctrl bits when re-arming interrupts ... The register write in ioat_dma_cleanup_tasklet is unfortunate in two ways: 1/ It clears the extra 'enable' bits that we set at alloc_chan_resources time 2/ It gives the impression that it disables interrupts when it is in fact re-arming interrupts [ Impact: fix, persist the value of the chanctrl register when re-arming ] Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>		2009-09-08 17:30:24 -07:00
