checkpatch.pl<http://checkpatch.pl> requires perl v5.10.0 to run but it
doesn't require to place in /usr/bin/perl
Use env to ensure that the interpreter used is the
first one on environment's $PATH on system with
several versions of perl installed.

Would it not work to pass in the -w here?

Yes it will not work just to pass -w
It's taking -w as a file.
