[dpdk-dev] [PATCH] devtools: pass custom options to checkpatch

[Olivier Matz <olivier.matz@6wind.com>]

Add the ability to pass custom options to checkpatch script. An example
of use is to change the output format so it can run in emacs compilation
mode:

  DPDK_CHECKPATCH_PATH=/path/to/linux/scripts/checkpatch.pl \
    DPDK_CHECKPATCH_OPTIONS='--emacs --showfile --no-color' \
    /path/to/dpdk.org/devtools/checkpatches.sh
