Subject: [PATCH v2 06/12] drm/msm/dp: Use drm_bridge_hpd_notify()
Date: Fri, 08 Aug 2025 17:35:18 -0700 [thread overview]
Message-ID: <20250808-hpd-refactor-v2-6-7f4e1e741aa3@oss.qualcomm.com> (raw)
In-Reply-To: <20250808-hpd-refactor-v2-0-7f4e1e741aa3@oss.qualcomm.com>
Call drm_bridge_hpd_notify() instead of drm_helper_hpd_irq_event(). This
way, we can directly call hpd_notify() via the bridge connector.
