From 6135ee07702781cd8206bcb1c202c4630d6e3c9c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 22 Feb 2022 17:40:36 +0100 Subject: [PATCH] drm/vc4: hdmi: Rename pixel_rate variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The pixel_rate field in the vc4_hdmi_connector_state struct actually stores the TMDS character rate, let's rename it for consistency.
