The flavour of awk that's installed by default on Ubuntu is 'mawk' which 
does
not seem to have a '-e' option. However, for anyone tryung to run 
checkpatch
on Ubuntu with this patch, the quickest workaround is to install 'gawk',
which does have the -e option, then this patch works great.

Rgds,
Dave.
