-Subject: [PATCH] drm/vc4: Disable V3D interactions if the v3d
- component didn't probe.
-
-Commit ffc26740714962e3e8801dca7ef32b636b3781db upstream.
-
-One might want to use the VC4 display stack without using Mesa.
-Similar to the debugfs fixes for not having all of the possible
-display bits enabled, make sure you can't oops in vc4 if v3d isn't
-enabled.
-
-v2: Fix matching against other v3d variants (review by Paul), don't
-    forget to set irq_enabled so that the vblank uapi works
-v3: Use -ENODEV instead of -EINVAL on Paul's suggestion.
