Russell,
Thanks I have applied this

Although gcc didnt like not handling other enums so warned:

drivers/dma/amba-pl08x.c: In function 'pl08x_width':
drivers/dma/amba-pl08x.c:1119: warning: enumeration value
'DMA_SLAVE_BUSWIDTH_UNDEFINED' not handled in switch
drivers/dma/amba-pl08x.c:1119: warning: enumeration value
'DMA_SLAVE_BUSWIDTH_8_BYTES' not handled in switch

which can be fixed as:

diff --git a/drivers/dma/amba-pl08x.c b/drivers/dma/amba-pl08x.c
index 9aa2bd4..4925e0d 100644
--- a/drivers/dma/amba-pl08x.c
+++ b/drivers/dma/amba-pl08x.c
@@ -1123,6 +1123,8 @@ static u32 pl08x_width(enum dma_slave_buswidth
width)
 		return PL080_WIDTH_16BIT;
 	case DMA_SLAVE_BUSWIDTH_4_BYTES:
 		return PL080_WIDTH_32BIT;
+	default:

 	}
 	return ~0;
 }

If you are okay, pls ack it
