Checkpatch
Checkpatch is the code-linter used for enforcing the Linux kernel C-code conventions. One can find more information about it in here
</path/to/>/checkpatch.pl --no-tree --file </path/to/examined/file.c>
If one shall desires to execute checkpatch on each & every .c file then he can use the following command:
find . -type f | grep "\.c$" | xargs </path/to/>/checkpatch.pl --no-tree --file
In our case, checkpath has being copied into the repo so we can execute:
find . -type f | grep "\.c$" | xargs ./scripts/checkpatch.pl --no-tree --file
