Subject: [PATCH 5/5] media: mtk-vcodec: venc: Fail if a msg sent to VPU was not signaled
Date: Wed,  4 Aug 2021 16:27:29 +0200	[thread overview]
Message-ID: <20210804142729.7231-6-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20210804142729.7231-1-dafna.hirschfeld@collabora.com>

Each message sent to the VPU should raise a signal. The signal
handler sets vpu->signaled. Test the field and fail
if it is 0.
