ide: kill ide_dma_submit_check
Merge ide_dma_submit_check into it's only caller. Also use tail recursion using a goto instead of a real recursion - this avoid overflowing the stack in the pathological situation of an recurring error that is ignored. We'll still be busy looping in ide_dma_cb, but at least won't eat up all stack space after this. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>
