[dpdk-stable] [PATCH v3 1/2] Enable codespell by default. Can be disabled from config file.

[Michael Santana]

Enable codespell by default.
codespell is a feature by checkpatch.pl that
checks for common spelling mistakes in patches.

This feature is disabled by default. To enable it one must add
the '--codespell' flag to the $options variable in
checkpatches.sh. With this change codespell is enabled by default.
The user can decide to turn off codespell from a one of the config
files read by checkpatches.sh.
