So renames the parameter to 'trace_chan_id'. It's luck to have a local variable 'trace_chan_id' in the function cs_etm__setup_queue(), even we wrongly define the macro TO_CS_QUEUE_NR, the local variable 'trace_chan_id' is used rather than the macro's parameter 'trace_id_chan'; so the compiler doesn't complain for this before. After renaming the parameter, it leads to a compiling error due cs_etm__setup_queue() has no variable 'trace_id_chan'. This patch uses the variable 'trace_chan_id' for the macro so that fixes the compiling error.
