checkpatch.pl and get_maintainer.pl currently reject sparse checkouts because their top_of_kernel_tree() checks require top-level directories that may not be present in a sparse working tree.

This series relaxes that check to match the files the scripts actually need and adds a regression test to keep that behavior from regressing.

Changes in v2:
  - add a regression test for sparse checkout handling in checkpatch.pl and
    get_maintainer.pl


CaoRuichuang (2):
  scripts: allow checkpatch and get_maintainer in sparse checkouts
  scripts: add sparse checkout regression test for checkpatch tools
