usb: musb: fix cppi channel teardown for isoch transfer
[ Upstream commit b431ba8803666e56c1d178a421b3cbc36e8d3d33 ]
After a few iterations of start/stop UVC camera streaming, the streaming
stops.
This patch adds 250us delay in the cppi channel abort path to let cppi
drain properly.
Using 50us delay seems to be too aggressive, some webcams are still
broken. 250us is the original value used in TI 3.2 kernel.
