dmaengine: pl08x: handle the rest of enums in pl08x_width
pl08x_width function does not handle rest of enums for DMA_SLAVE_BUSWIDTH_xxxx which causes gcc to emit below warining 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 this patch adds a default case which returns error Signed-off-by: Vinod Koul <vinod.koul@intel.com>
