dmaengine: tegra-apb: Remove unused variables
The callback and callback_param members of the tegra_dma_sg_req structure are never used. The dma-engine structure, dma_async_tx_descriptor, defines the same members and these are the ones used by the driver. Therefore, remove the unused versions from the tegra_dma_sg_req structure. The half_done member of tegra_dma_channel structure is configured but never used and so remove it. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
