dmaengine: owl: Fix warnings generated during build
Following warnings are generated when compiled with W=1, drivers/dma/owl-dma.c:170: warning: Function parameter or member 'cyclic' not described in 'owl_dma_txd' drivers/dma/owl-dma.c:198: warning: Function parameter or member 'cfg' not described in 'owl_dma_vchan' drivers/dma/owl-dma.c:198: warning: Function parameter or member 'drq' not described in 'owl_dma_vchan' drivers/dma/owl-dma.c:225: warning: Function parameter or member 'irq' not described in 'owl_dma' Fix this by adding comments for relevant struct members to appear in kernel-doc.
