From 078ab3ea2c3bb69cb989d52346fefa1246055e5b Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 5 Dec 2018 12:23:54 -0500 Subject: media: Add a Kconfig option for the Request API The Request API is now merged to the kernel but the confidence on the stability of that API is not great, especially regarding the interaction with V4L2. Add a Kconfig option for the API, with a scary-looking warning. The patch itself disables request creation as well as does not advertise them as buffer flags. The driver requiring requests (cedrus) now depends on the Kconfig option as well.
