Subject: [PATCH v2 02/15] drm/i915/hotplug: Handle CP_IRQ for DP-MST
Date: Tue, 20 Oct 2020 19:08:53 +0530	[thread overview]
Message-ID: <20201020133906.23710-3-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201020133906.23710-1-anshuman.gupta@intel.com>

Handle CP_IRQ in DEVICE_SERVICE_IRQ_VECTOR_ESI0
It requires to call intel_hdcp_handle_cp_irq() in case
of CP_IRQ is triggered by a sink in DP-MST topology.
