Building kernel with W=1 throws below invalid assignment warnings.
bam_dma.c:676:44: warning: invalid assignment: +=
bam_dma.c:676:44: left side has type unsigned long
bam_dma.c:676:44: right side has type restricted __le16
bam_dma.c:921:41: warning: invalid assignment: +=
bam_dma.c:921:41: left side has type unsigned long
