From 218fc9f2fcfbad70e7b2111eca591b1dc8e6c8a9 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 10 Feb 2020 11:42:38 +0100 Subject: media: Documentation/media/uapi: more readable unions Avoid adding an extra columns when describing unions in the documentation. That makes it much harder to read. See e.g. VIDIOC_QUERY_EXT_CTRLS. Instead start off a union with 'union {' and end it with an extra row containing '}'. This leaves a lot more space for the description of the fields. This formatting technique was used in a few places already, but this patches fixes all remaining occurrences of 'union' in the media uAPI.
