    Subject[PATCH v2 04/10] drm/framebuffer: Use actual bpp for DRM_IOCTL_MODE_GETFB
    Date
    When userspace queries the properties of a frame buffer, the number of
    bits per pixel is derived from the deprecated drm_format_info.cpp[]
    field, which does not take into account block sizes.

    Fix this by using the actual number of bits per pixel instead.
