Subject: [patch 3/9] scripts/spdxcheck: Add [sub]directory statistics
Add functionality to display [sub]directory statistics. This is enabled by
adding '-d' to the command line. The optional -D parameter allows to limit
the directory depth. If supplied the subdirectories are accumulated
# scripts/spdxcheck.py -d kernel/
Incomplete directories: SPDX in Files
./kernel : 111 of 114 97%
./kernel/bpf : 43 of 45 95%
./kernel/bpf/preload : 4 of 5 80%

./kernel/debug/kdb : 1 of 11 9%
./kernel/locking : 29 of 32 90%
./kernel/sched : 38 of 39 97%
The result can be accumulated by restricting the depth via the new command
line option '-d $DEPTH':
