Subject: Re: [PATCH] media: mediatek: vcodec: Fix an error handling path in
 vdec_msg_queue_init()

Hi Christophe,

This no longer applies after some major rework of the driver from Yunfei that
was merged to our media_stage tree.

Can you rebase this patch (if it is even still relevant)?

Thanks,

	Hans
