Commit Message

Peter Ujfalusi June 10, 2022, 8:04 a.m. UTC 
The dmesg log message of "Firmware exception" causes lots of confusion as
the snd_sof_handle_fw_exception() is only called in case of an IPC tx
timeout, where such a message does not make much sense.

To not limit the snd_sof_handle_fw_exception() handler to just one error
case, add a parameter to allow the caller to specify a meaningful message
to be printed.
