Sorry, I did not realise something was blocked because of me, specially imx8
related. I thought you have sent the update to MAINTAINERS.

For me it is fine, it makes perfect sense since you have access to hardware
and documentation, for you to be the maintainer and steer the features and 
improvements in the imx media. you can move me to Reviewer, since there are
already other 2 persons (and Laurent already handle the pulls, thanks for that)
much more active in the IMX media subsystem.

Thanks again and Cheers,
    Rui
