[PATCH next] pinctrl: bcm281xx: Add missing assignment in bcm21664_pinctrl_lock_all()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The next line checks if this regmap_write() failed, but it doesn't
work because the assignment was accidentally left out.  Add the
assignment.

Fixes: 60d69769c851 ("pinctrl: bcm281xx: Add support for BCM21664 pinmux")
