[PATCH] gpio: fix build failure: gpiochip_[un]lock*() static/non-static

[John Hubbard]

While building with !CONFIG_GPIOLIB, I experienced a build failure,
because driver.h in that configuration supplies both a static and
a non-static version of these routines:

	gpiochip_lock_as_irq()
	gpiochip_unlock_as_irq()

Fix this by moving the non-static routines under the scope of
CONFIG_GPIOLIB.

Fixes: commit c7663fa2a663 ("gpio: Move gpiochip_lock/unlock_as_irq to gpio/driver.h")

Hi,

This is for today's linux-next.

More background:

It *looks* like the original commit did correctly put the non-static
versions of these routines in CONFIG_GPIOLIB, and the static versions
inside !CONFIG_GPIOLIB, but my git history foo is not strong enough
to figure out how we got here, so I'm not sure if the "Fixes:" tag
really refers to the guilty commit.

thanks,
John Hubbard
