[PATCH] ARM: footbridge: fix build warning

[Linus Walleij]

The raw spinlock in the netwinder GPIO implementation was using
non-raw accessors, fix this warning from the autobuilder:

arch/arm/mach-footbridge/netwinder-hw.c:695:2:
warning: passing argument 1 of 'spinlock_check' from
incompatible pointer type [enabled by default]
arch/arm/mach-footbridge/netwinder-hw.c:702:2:
warning: passing argument 1 of 'spin_unlock_irqrestore' from
incompatible pointer type [enabled by default]
arch/arm/mach-footbridge/netwinder-hw.c:712:2:
warning: passing argument 1 of 'spinlock_check' from
incompatible pointer type [enabled by default]
arch/arm/mach-footbridge/netwinder-hw.c:714:2:
warning: passing argument 1 of 'spin_unlock_irqrestore' from
incompatible pointer type [enabled by default]

I've already got this in my tree.  Thanks anyway.
