Since users prefer different fbcon cursor blink intervals, allow the
interval to be set via sysfs. The current interval of 200 milliseconds
is retained as the default. Tested with intelfb.

v2:  Use kstrtos16() instead of kstrtoul() and min_t() as suggested by
     Geert Uytterhoeven
v3:  Add error messages as suggested by Tomi Valkeinen
v4:  Add rationale into patch descriptions as suggested by
     Richard Weinberger

Hehe, no need to resend immediately a v4, I'm just curios about the use case. :)
Why do users want a different blink interval? What is the use case?
And what are these users? Most people use a fbcon only for a few moments
to fix/restart X11.

Ah, I see! With multiple ncurses windows, some of which contain reversed 
characters, a blinking underscore is helpful for locating the cursor.
But, the 200 millisecond interval can be distracting. Another example is
