+Subject: [PATCH] drm/vc4/vc4_hdmi_regs: Mark some data sets as
+ __maybe_unused
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The alternative is to move them into the source file that uses then,
+but they are large and intrusive, so that strategy is being avoided.
+
+Fixes the following W=1 kernel build warning(s):
+
+ drivers/gpu/drm/vc4/vc4_hdmi_regs.h:282:39: warning: ‘vc5_hdmi_hdmi1_fields’ defined but not used [-Wunused-const-variable=]
+ drivers/gpu/drm/vc4/vc4_hdmi_regs.h:206:39: warning: ‘vc5_hdmi_hdmi0_fields’ defined but not used [-Wunused-const-variable=]
+ drivers/gpu/drm/vc4/vc4_hdmi_regs.h:145:39: warning: ‘vc4_hdmi_fields’ defined but not used [-Wunused-const-variable=]
