When allocating a frame buffer, the number of bits per pixel needed is derived from the deprecated drm_format_info.cpp[] field. While this works for formats using less than 8 bits per pixel, it does lead to a large overallocation.
Reduce memory consumption by using the actual number of bits per pixel instead.
