Subject: oe/license_finder: support extra hashes being passed to find_licenses
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9011bc307fcdccb144b75d77b36bbc5c8d4bd96d;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

oe/license_finder: support extra hashes being passed to find_licenses

When using the license finder the caller might know some more license
hashes, for example if it is updating existing metadata.

Allow the caller to pass more hashes that can be used when identifying
licenses.
