If I am not wrong, this change creates crash in v4.4.y. As before calling con_scrolldelta, NULL check is missing inside console_callback() for v4.4.y, refer: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/driver...
This NULL check was added in commit 97293de977365fe672daec2523e66ef457104921, and this is not merged to v4.4.y
Good catch, will go queue up that portion of that commit to 4.4.y now, thanks!
