Subject: change ply_window_new to take a device instead of vt number
X-Git-Tag: 0.6.0~90
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fbaa2f980535f698f42745875786777efb9157fa;p=thirdparty%2Fplymouth.git

change ply_window_new to take a device instead of vt number

We're going to wrap windows around serial devices, too.
