Convert all uses of error_report("[Ww]arning:"... to use warn_report()
instead. This helps standardise on a single method of printing warnings
to the user.

All of the warnings were changed using this command:
    find ./* -type f -exec sed -i \
    's|error_report.*[Ww]arning: |warn_report("|g' {} +

Then the white space changes where manually fixed afterwards.

The test-qdev-global-props test case was manually updated to ensure that
this patch passes make check (as the test cases are case sensitive).

You reindented consecutive lines everywhere else, so you may want to do
that here, too.

With that fixed (or even without, as evidently the alignment for
error_report() wasn't quite right all the time either), for block*:

They were not; see evidence inline.  Please provide the exact script you
use, and punt all the cases it doesn't convert to the manual patch.
