The modetest application uses libkms to allocate dumb buffers, leading to overallocation due to the hardcoded 32 bpp value. This can even cause failures in drivers when the resulting pitch is too large for the hardware to handle and gets rejected by the driver when creating the frame buffer. Fix this by computing the required bpp value and allocating dumb buffers directly without going through libkms. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
