Subject: [PATCH 3.18 17/47] clk: at91: usb: fix determine_rate prototype again

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

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

From: Arnd Bergmann <arnd@...db.de>

We had an incorrect backport of
4591243102fa ("clk: at91: usb: propagate rate modification to the parent clk")
that was fixed incorrectly in linux-3.18.y by
76723e7ed589 ("clk: at91: usb: fix determine_rate prototype")

as shown by this warning:

drivers/clk/at91/clk-usb.c:155:20: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
drivers/clk/at91/clk-usb.c:193:20: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]

This should fix it properly.
