+Subject: [PATCH 4073/4256] drm/amd/display: Fix maybe-uninitialized warning
+
+[Why]
+
+Compiling with GCC 9.1.0 gives the following warning (I have
+warnings-as-errors enabled):
+
+drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/core/dc.c: In function 'dc_validate_seamless_boot_timing':
+drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/core/dc.c:1180:8: error: 'se' may be used uninitialized in this function [-Werror=maybe-uninitialized]
+ 1180 |   if (!se->funcs->dp_get_pixel_format(
+      |        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ 1181 |    se,
+      |    ~~~
+ 1182 |    &hw_crtc_timing.pixel_encoding,
+      |    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ 1183 |    &hw_crtc_timing.display_color_depth))
+
+[How]
+
+Initialize se to NULL.
