I did not have the HW see the problem myself, but reading from the code the problem is evident. This should also fix Dan Carpenter's concern about stack usage in davinci_mcasp_hw_rule_channels(), as the whole function is removed. The second patch is just an optimization of the sample-rate rule. In effect I put in use Takashi Iwai's suggestion for fixing the stack usage issue in the channels rule.
