+Subject: [PATCH] bcm2708_fb: Fix layout of struct
+ vc4_display_settings_t
+
+The display parameters returned by the VC4 firmware in response to the
+RPI_FIRMWARE_FRAMEBUFFER_GET_DISPLAY_SETTINGS tag do not match the
+layout of struct vc4_display_settings_t: the colour depth and row
+pitch are erroneously swapped in the kernel definition.  This can
+trigger a kernel warning from pixel_to_pat(), such as:
+
+  pixel_to_pat(): unsupported pixelformat 7296
+
+Fix by adjusting the layout of struct vc4_display_settings_t to match
+the layout as used by the VC4 firmware.
