3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tao Hou <[email protected]> [ Upstream commit ffb5ba90017505a19e238e986e6d33f09e4df765 ] chan->count is used by rx channel. If the desc count is not updated by the clean up loop in cpdma_chan_stop, the value written to the rxfree register in cpdma_chan_start will be incorrect.
