usb: cdns3: change some trace event __dynamic_array() to __get_buf()

2023-03-09T14:35:03Z

some __dynamic_array() buffer will only used at trace event output time, change to __get_buf() which will allocate tempary trace seq buffer for output purpose.

usb: cdns3: change trace event cdns3_ring() operation

2023-03-09T14:35:03Z

the original design seem have several problems, first during trace event output stage, cdns3_dbg_ring() still refer to priv_ep->trb_pool which data content may changed during runtime, second when ring number is greater than TRBS_PER_SEGMENT, it has no change to show "too big" message, third in cdns3_log_ring event class definition, it allocate too much trace event buffer. change cdns3_dbg_ring() to be called at trace event fast assign time, and change trace buffer real dynamic according ring numbers.

usb: cdns3: trace: delete the trace parameter for request->trb

2021-04-12T12:19:21Z

It is not correct using %pa to print virtual address of request->trb, and it is hard to print its physical address due to the virtual address is zero before using. It could use index (start_trb/end_trb) to know the current trb position, so no matter virtual address or physical address for request-trb is not so meaningful.
