I was asking a question, not making a statement.
There is no need to blow a fuse or yell via exclamation marks at people
who provide 90% of the patches for the subsystem you maintain, or
provide fixes for your own patches.

I accept the argument, I just didn't understand what the issue was.

ok, so we will change the title to 'soundwire: intel: add error log for
clock-stop invalid config'.
