From 51df3c81ba10b00f4da81225310a3503b0583062 Mon Sep 17 00:00:00 2001 From: Stanimir Varbanov Date: Tue, 31 Mar 2020 18:19:51 +0200 Subject: [PATCH] media: venus: vdec: Mark flushed buffers with error state Once the hfi_session_flush is issued by the vdec all queued buffers to firmware should be returned to the v4l driver. Some of those buffers are not processed at the time of flush command, those buffers has filled len zero (no data). Catch that in buffer_done callback and mark not filled capture buffers with error state so that client can discard them.
