Subject: [PATCH] drm/vc4: crtc: Provide a CRTC name
|
|
|
|
It's fairly hard to figure out the instance of the CRTC affected by an
|
|
atomic change using the default name.
|
|
|
|
Since we can provide our own to the CRTC initialization functions, let's
|
|
do so to make the debugging sessions easier.
