If checkpatch.pl gets copied out of the tree, --no-tree shouldn't start
complaining:
Use of uninitialized value $root in concatenation (.) or string at
/path/to/checkpatch.pl line 764.
Let's just give the safe answer instead -- don't warn about "obsolete"
files.
Fixes: 85b0ee18bbf8 ("checkpatch: see if modified files are marked obsolete in MAINTAINERS")

Actually, I'm torn on this. It looks really odd to check for !$tree
here, but it's the only supported case where $root shouldn't be defined.
Maybe (!defined $root) is a better test? (Sorry, I did a double-take on
this after I sent it.)
Both would be equally correct, but I suppose the latter would be
clearer. I'll send v2.

Sure, good enough. Though it does have the same tiny awkwardness as my
v1.
