Subject: [PATCH] gbefb: IP32 gbefb depth change fix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=68b06deb2b343c040485a9fc6c813577bf6d5cf5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] gbefb: IP32 gbefb depth change fix

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).
