Subject: Support disabling warnings for redundant assignments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Linux Kernel's merge_config.sh defaults to disabling warnings for
redundant assignments and has support for enabling them
specifically. This patch reproduces this behaviour in kconfiglib
except that we retaing kconfiglib's default behaviour of enabling the
warnings.
