Since commit 875a4d536842 ("drm/vc4: drv: Disable the CRTC at boot
time"), during the initial setup of the driver we call into the VC4 HDMI
controller hooks to make sure the controller is properly disabled.
However, we were never making sure that the device was properly powered
while doing so. This never resulted in any (reported) issue in practice,
but since the introduction of commit 4209f03fcb8e ("drm/vc4: hdmi: Warn
if we access the controller while disabled") we get a loud complaint
when we do that kind of access.
[...]Applied to drm/drm-misc (drm-misc-fixes). Thanks! Maxime _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
