Subject: mm/damon/tests: use scoped_guard() for damon_test_ops_registration
Date: Mon, 31 Aug 2026 07:26:07 -0700

Replace manual mutex_lock() and mutex_unlock() calls with the
scoped_guard() macro.  This simplifies the code, improves readability, and
ensures that the lock is automatically released when the scope ends,
preventing potential lock leaks in the future.
