patch "fbcon: initialize blink interval before calling fb_set_par" added to tty-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    fbcon: initialize blink interval before calling fb_set_par

to my tty git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: fbcon: initialize blink interval before calling fb_set_par

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.
