patches/old/devdax-minor-warning-fixups.patch

From: Dan Williams <dan.j.williams@intel.com>
Subject: devdax: minor warning fixups
Date: Fri, 14 Oct 2022 16:58:14 -0700

Fix a missing prototype warning for dev_dax_probe(), and fix dax_holder()
comment block format.  These are holdover fixes that are now being
addressed as some fsdax infrastructure is being moved into the dax core.
