Subject: checkpatch: skip CamelCase cache for --no-tree without root
Date: Mon, 10 Aug 2026 18:11:59 +0200

Running outside tree (--no-tree) without git root (--root DIR) is not
doable because we have no include/ directory which could be cached.  But
3445686af721 expected that we are always in Linux tree (w/a git).  But
--no-tree does not require --root.  Therefore skip whole caching in that
case.

This fixes perl and find errors when running checkpatch.pl *with*
--no-tree --strict and *without* --root:

    No structs that should be const will be found - file 'scripts/const_structs.checkpatch': No such file or directory
    Use of uninitialized value $root in concatenation (.) or string at scripts/checkpatch.pl line 1213.
    find: `/include': No such file or directory
