(the data structure does not match the firmware definition) commit 26f64fa81357f4b18192432eb8023f99c7eb5cf7 (HEAD -> 26f64fa81357f4b18192432eb8023f99c7eb5cf7) Author: Michael Brown <[email protected]> Date: Sun Sep 22 21:51:29 2019 +0100 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.
