By removing this line, you are effectively not assigning d->lch_count after reserving. So the patch should only change dma_lch_count in the above "if statement" to d->lch_count Regards, Sricharan -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
