openwrt/target/linux/bcm27xx/patches-5.4/950-0567-drm-vc4-hdmi-Rename-hdmi-to-vc4_hdmi.patch

From 02b7a6ed6b9fc110dd26598d26c31c0837af6184 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>
Date: Mon, 6 Jan 2020 18:07:05 +0100
Subject: [PATCH] drm/vc4: hdmi: Rename hdmi to vc4_hdmi

The driver isn't consistent with the name given to the vc4_hdmi
structure pointer in its functions. Make sure to use a consistent name.
