[PATCH v2 6/6] media: uvcvideo: Set a different name for the metadata entity

From: Ricardo Ribalda
Date: Thu Mar 11 2021 - 17:21:08 EST


All the entities must have a unique name.

Fixes v4l2-compliance:
Media Controller ioctls:
fail: v4l2-test-media.cpp(205): v2_entity_names_set.find(key) != v2_entity_names_set.end()
test MEDIA_IOC_G_TOPOLOGY: FAIL
fail: v4l2-test-media.cpp(394): num_data_links != num_links
test MEDIA_IOC_ENUM_ENTITIES/LINKS: FAIL
