This patch seems to be a way to manipulate a device tree property in the
Linux device tree. How about adding a new option to the of_property
command which would register a of_fixup instead of doing the operation
now?
Like this:
of_property -f -s /path/to/node compatible vendor,foo-display

xstrdup() is what you want here.
