Subject: ply-device-manager: Add syspath_is_simpledrm () helper
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1c3ff0338c80a831b2f0ea63a57e20c9013ddb52;p=thirdparty%2Fplymouth.git

ply-device-manager: Add syspath_is_simpledrm () helper

Add a helper to determine if a udev syspath is a simpledrm device.
This is a preparation patch to for making simpledrm devices their
own renderer-type.
