#1264470 — [PATCH 4.2 075/110] fbcon: initialize blink interval before calling fb_set_par

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Scot Doyle <lkml14@scotdoyle.com>

commit f235f664a8afabccf863a5dee4777d2d7b676fda upstream.

Since commit 27a4c827c34ac4256a190cc9d24607f953c1c459
    fbcon: use the cursor blink interval provided by vt

a PPC64LE kernel fails to boot when fbcon_add_cursor_timer uses an
uninitialized ops->cur_blink_jiffies. Prevent by initializing
in fbcon_init before the call to info->fbops->fb_set_par.
