From 79e85d1d2c16ba4907bb9d6a4381516b729ff341 Mon Sep 17 00:00:00 2001 From: Guillaume Tucker Date: Wed, 24 Jul 2019 11:19:22 -0400 Subject: [PATCH] media: vivid: fix device init when no_error_inj=1 and fb disabled Add an extra condition to add the video output control class when the device has some hdmi outputs defined. This is required to then always be able to add the display present control, which is enabled when there are some hdmi outputs. This fixes the corner case where no_error_inj is enabled and the device has no frame buffer but some hdmi outputs, as otherwise the video output control class would be added anyway. Without this fix, the sanity checks fail in v4l2_ctrl_new() as name is NULL.
