With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.
Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

This patch replaces all dev_vdbg calls with tracepoints to reduce
overhead and enable use of trace collection and analysis tools.

The Intel HDaudio controller relies on a single interrupt line which
wire-ORs multiple interrupt sources, such as stream, IPC, SoundWire and
wakes. This patch adds the ability to trace each event occurrence.
