[PATCH] ioat: remove chanerr mask setting for IOAT v3.x

2012-11-16 Thread Dave Jiang
The CHANERRMSK_INT register should be 0. The existing code set a value for a workaround to address a pre-silicon bug on the Intel 5520 IO hub that has been fixed when the hardware was released. There is no need for this code. Signed-off-by: Dave Jiang --- drivers/dma/ioat/dma_v3.c |8 ++
