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.
