Subject: ply-renderer: Add new PLY_RENDERER_TYPE_SIMPLEDRM renderer-type
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19d49a42fcc3cf9d3ee62a572eec24e8b73f9799;p=thirdparty%2Fplymouth.git

ply-renderer: Add new PLY_RENDERER_TYPE_SIMPLEDRM renderer-type

Add a new PLY_RENDERER_TYPE_SIMPLEDRM renderer-type to help differentiate
the simpledrm case from the regular drm device case.

simpledrm devices require some special handling in the device-manager,
this is a preparation patch for improving the simpledrm handling
in ply-device-manager.
