[PATCH 0/2] Fix CPPI Warnings during tear down after ISOCH transfers

[George Cherian]

Warinings are seen after  ISOCH transfers, during channel tear down.
This is mainly beacause we handle ISOCH differently as compared to 
other transfers. 

Patch 1: make sure we do channel tear down only if channel is busy.
	 If not the tear down will never succeed.

Patch 2: ISOCH completions are done differently, so this might lead to 
	reprogram of dma channel on which already a teardown is done.
	

George Cherian (2):
  dma: cppi41: start tear down only if channel is busy
  usb: musb: musb_cppi41: Dont reprogram DMA if tear down is initiated
