[PATCH 11/38] media: vivid: move set_capabilities logic to a separate function

From: Mauro Carvalho Chehab
Date: Wed Sep 02 2020 - 12:18:52 EST


Move such logic from vivid_create_instance(), as otherwise
smatch takes forever.

The vivid_create_instance() is still a too big for my taste.
So, further cleanups are still needed.
