Subject: Re: [PATCH 3/3] media: mtk-vcodec: Separating mtk encoder driver
Hi Irui,
Thanks for pushing this forward. I had two small conflicts when
applying this patch to the media tree, so you may want to rebase
before sending the next version. Please see the comments inline.

Also the patch does not result in two drivers, but two devices.

I wonder if we need to use two different names? The driver is the
same, so it makes sense to me that both devices return
"mtk-vcodec-enc". Userspace can then list the formats on the CAPTURE
queue in order to query the supported codecs.

This new member can be removed if we use the same name for both devices.

Let's keep the indendation at the same level as before (if we use the
same driver name for both devices this change is unnecessary though).
