+## DP: IP32 gbefb depth change fix
+## Upstream status: submitted to linux-fbdev-devel (Antonino A. Daplas)
+
+# The gbefb driver does not update the framebuffer layers visual
+# setting when depth is changed with fbset, resulting in strange
+# colors (very dark blue in 16-bit, almost black in 24-bit).
+# The attached patch fixes that.
