Subject: mm/damon/dbgfs-test: skip dbgfs_set_init_regions() test if PADDR is not registered
Date: Mon, 26 Aug 2024 20:03:34 -0700

The test depends on registration of DAMON_OPS_PADDR.  It would be
registered only when CONFIG_DAMON_PADDR is set.  DAMON core kunit tests do
fake ops registration for such case.  However, the functions for such fake
ops registration is not available to DAMON debugfs interface.  Just skip
the test in the case.
