Subject: Stop bailing out on unknown firmwares
X-Git-Tag: yubikey-personalisation_1.3-1~2^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d8733a21d04cbb97b50ed6fbac531cc27c0ef4d;p=yubikey-personalization.old

Stop bailing out on unknown firmwares

Previously, we would bail out if we saw an unsupported firmware.  Stop
doing that and instead write out a warning message saying not all
features might be supported.
