Subject: [PATCH v4 02/16] drm/i915/hdcp: Get conn while content_type changed
Date: Tue, 27 Oct 2020 22:11:54 +0530 [thread overview]
Message-ID: <20201027164208.10026-3-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201027164208.10026-1-anshuman.gupta@intel.com>
Get DRM connector reference count while scheduling a prop work
to avoid any possible destroy of DRM connector when it is in
DRM_CONNECTOR_REGISTERED state.
