Add checkpatch configuration file
Capture checkpatch.pl command line arguments in .checkpatch The file
assumes some processing when used:
- Lines starting with # shall be removed.
- Shell variables have to be evaluated.
The above can be done when using bash like:
checkpatch.pl $(eval echo $(sed 's/#.*//g; /^$/d' ".checkpatch"))
Note: the eval imposes a security risk as it will execute unknown code
from .checkpatch. A solution can be to replace variables with their
values like:
sed 's/#.*//g; /^$/d' ".checkpatch"\
| sed "s#\$CODESPELL_FILE#$CODESPELL_FILE#"
