[PATCH] ARM: nomadik: fix clocksource warning

[PATCH] ARM: nomadik: fix clocksource warning

[Arnd Bergmann]

The clocksource API has changed slightly, which causes a harmless
warning:

/git/arm-soc/drivers/clocksource/nomadik-mtu.c:259:28: warning: 'nmdk_timer_match' defined but not used [-Wunused-variable]
 static struct of_device_id nmdk_timer_match[] __initconst = {
                            ^

Fortunately, the same API change also lets us simplify the code
while removing the warning.

I've applied this patch on top of next/dt to remove the warning introduced
by Linus' patch.

I didn't see that make it to the repo though?

Since you'd have to rebase anyway, I'll just apply it here and will
include it with the other branch updates.

Thanks. I had applied it locally but then forgot to push it out.

Ah so it matches the string directly in CLOCKSOURCE_OF_DECLARE()
OK makes perfect sense, sometimes it's hard to keep up with
the evolutional pace here...
