In the Linux kernel, the following vulnerability has been resolved:drm/vc4: hdmi: Avoid hang with debug registers when suspendedTrying to read /sys/kernel/debug/dri/1/hdmi1_regswhen the hdmi is disconnected results in a fatal system hang.This is due to the pm suspend code disabling the dvp clock.That is just a gate of the 108MHz clock in DVP_HT_RPI_MISC_CONFIG,which results in accesses hanging AXI bus.Protect against this.
