Subject: drm/vc4: hdmi: Rename pixel_rate variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 6135ee07702781cd8206bcb1c202c4630d6e3c9c
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The pixel_rate field in the vc4_hdmi_connector_state struct actually
stores the TMDS character rate, let's rename it for consistency.
