Subject: [PATCH 28/29] drm/amdgpu: wait_for_idle for each vcn instance
Date: Tue, 29 Oct 2024 13:42:39 -0400	[thread overview]
Message-ID: <20241029174240.682928-29-boyuan.zhang@amd.com> (raw)
In-Reply-To: <20241029174240.682928-1-boyuan.zhang@amd.com>

From: Boyuan Zhang <boyuan.zhang@amd.com>

Perform wait_for_idle only for the instance of the current vcn IP block,
instead of perform it for all vcn instances.

v2: remove unneeded local variable initialization.
