After fixing the following checkpatch errors:

ERROR: open brace '{' following function declarations go on the next line
#120: FILE: drivers/dma/apbh_dma.c:579:
+int mxs_dma_init_channel(int channel) {

ERROR: that open brace { should be on the previous line
#195: FILE: drivers/mtd/nand/mxs_nand.c:1076:
+	for (j = MXS_DMA_CHANNEL_AHB_APBH_GPMI0;
+		j <= MXS_DMA_CHANNEL_AHB_APBH_GPMI7; j++)
+	{

total: 2 errors, 0 warnings, 137 lines checked

Applied to u-boot-imx, thanks.

Best regards,
