Ugh, my bad. MEDIA_CONTROLLER_REQUEST_API can't
depend on staging, after this recently merged commit:

"media: Kconfig: Don't expose the Request API option"

So, we should fix that with:

diff --git a/drivers/media/mc/Kconfig b/drivers/media/mc/Kconfig
index 7c9628f37196..4815b9dde9af 100644
--- a/drivers/media/mc/Kconfig

 config MEDIA_CONTROLLER_REQUEST_API

-       depends on MEDIA_CONTROLLER && STAGING_MEDIA
+       depends on MEDIA_CONTROLLER
        help
          DO NOT ENABLE THIS OPTION UNLESS YOU KNOW WHAT YOU'RE DOING.
 
Mauro what do you think?
