Subject: [PATCH] drm/vc4: Remove conflicting framebuffers before
|
||
|
callind bind_all
|
||
|
|
||
|
The bind hooks will modify their controller registers, so simplefb is
|
||
|
going to be unusable anyway. Let's avoid any transient state where it
|
||
|
could still be in the system but no longer functionnal.
