The patch titled
fbcon: Revise primary device selection
has been removed from the -mm tree. Its filename was
fbcon-revise-primary-device-selection.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: fbcon: Revise primary device selection
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
Use set_con2fb_map() to select the primary display driver instead of using
unbind_con_driver() and bind_con_driver(). Using the former is much simpler
and safer than the current one.
