Subject: mm/damon/dbgfs: make debugfs interface deprecation message a macro
Date: Mon, 29 Jan 2024 17:35:43 -0800

DAMON debugfs interface deprecation message is written twice, once for the
warning, and again for DEPRECATED file's read output.  De-duplicate those
by defining the message as a macro and reuse.
