I don't see why we would want to do that, the FB console is traditionally (x86) good to alwaýs get up, as serial console might not always be available. For example for people who can't solder special cables but still want to boot a custom ROM on their Nexus. So I'd say keep it like this. Yours, Linus Walleij

Add the CMA (Contiguous Memory Allocator) for the MSM DRM driver, the simple panel, and the TI LM3630A driver in order to support the display on the LG Nexus 5 (hammerhead) phone. Signed-off-by: Brian Masney <masneyb@onstation.org> --- The panel and backlight are currently compiled into the kernel, but will be moved to be modules once the display is fully working in a later verison of this patch series. arch/arm/configs/qcom_defconfig | 5 +++++ 1 file changed, 5 insertions(+)
