Hi Takashi,
Removing FW_LOADER_USER_HELPER_FALLBACK leads to a failure in our HQVDP firmware execution. Indeed, our firmware is not built-in. It is a proprietary firmware uploaded into the file system that's why we need the USER_HELPER_FALLBACK to be able to load it once file system is available.

The commit [4fdbc678fe4d: drm: sti: add HQVDP plane] added the select of CONFIG_FW_LOADER_USER_HELPER_FALLBACK by some unwritten reason. But this config is known to be harmful, and is present only for compatibility reason for an old exotic system that mandates udev interaction which isn't supposed to be selected by a driver. Let's remove it.
