+Subject: [PATCH] modesetting: Fix 16 bit depth/bpp mode
+
+When setting DefaultDepth to 16 in the Screen section, the current
+code requests a 32 bpp framebuffer, however the X-Server seems to
+assumes 16 bpp.
+
+Fixes commit 21217d02168d ("modesetting: Implement 32->24 bpp
+conversion in shadow update")
+
+Signed-off-by: Stefan Agner <stefan@agner.ch>
