4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mikulas Patocka <mpato...@redhat.com>
commit 0ac319b7af1bb24a33365d0ec82a2f56a59b2a78 upstream.
Set the variable "line_length" in the function dlfb_ops_set_par. Without
this, we get garbage if we select different videomode with fbset.
