[PATCH v5 1/2] fbcon: store cursor blink interval in fbcon_ops

From: Scot Doyle <hidden>
Date: 2015-01-30 08:45:16
Also in: lkml
Subsystem: console subsystem, framebuffer layer, the rest · Maintainers: Greg Kroah-Hartman, Helge Deller, Linus Torvalds

fbcon toggles cursor display state every 200 milliseconds when blinking.
Since users prefer different toggle intervals, prepare to expose the
interval via sysfs by moving it to fbdev_ops and setting the default
to 200 milliseconds.
