From ccac77dc716530a408fc6b9fc4fa66d8dd780d62 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 3 Feb 2018 13:06:01 -0500 Subject: media: document the reservedX fields in media_v2_topology The MEDIA_IOC_G_TOPOLOGY documentation didn't document the reservedX fields. Related to that was that the documented type of the num_* fields was also wrong. Fix both.
