Subject: [PATCH] gpio: fix incorrect merge of linux/gpio/driver.h

Two otherwise correct patches got merged incorrectly, which leads to
build problems when CONFIG_GPIOLIB is disabled:

include/linux/gpio/driver.h:722:19: error: static declaration of 'gpiochip_lock_as_irq' follows non-static declaration
static inline int gpiochip_lock_as_irq(struct gpio_chip *chip,
                  ^
include/linux/gpio/driver.h:706:5: note: previous declaration is here
int gpiochip_lock_as_irq(struct gpio_chip *chip, unsigned int offset);
    ^
include/linux/gpio/driver.h:729:20: error: static declaration of 'gpiochip_unlock_as_irq' follows non-static declaration
static inline void gpiochip_unlock_as_irq(struct gpio_chip *chip,
                   ^
include/linux/gpio/driver.h:707:6: note: previous declaration is here
void gpiochip_unlock_as_irq(struct gpio_chip *chip, unsigned int offset);

Fixes: 8a6abcd04e4c ("Merge tag 'gpio-v5.4-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into devel")
Fixes: 9091373ab7ea ("gpio: remove less important #ifdef around declarations")
Fixes: c7663fa2a663 ("gpio: Move gpiochip_lock/unlock_as_irq to gpio/driver.h")
