[PATCH 4.1 136/267] drm/bridge: ptn3460: Include linux/gpio/consumer.h

[Greg Kroah-Hartman]

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

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

From: Geert Uytterhoeven <geert at linux-m68k.org>

commit dad3c3503462f59c6bec7edfa19dbde1857962c0 upstream.

If GPIOLIB=n and asm-generic/gpio.h is not used:

    drivers/gpu/drm/bridge/ptn3460.c: In function ‘ptn3460_pre_enable’:
    drivers/gpu/drm/bridge/ptn3460.c:135: error: implicit declaration of function ‘gpiod_set_value’
    drivers/gpu/drm/bridge/ptn3460.c: In function ‘ptn3460_probe’:
    drivers/gpu/drm/bridge/ptn3460.c:333: error: implicit declaration of function ‘devm_gpiod_get’
    drivers/gpu/drm/bridge/ptn3460.c:333: warning: assignment makes pointer from integer without a cast
    drivers/gpu/drm/bridge/ptn3460.c:340: error: implicit declaration of function ‘gpiod_direction_output’
    drivers/gpu/drm/bridge/ptn3460.c:346: warning: assignment makes pointer from integer without a cast

Add the missing #include <linux/gpio/consumer.h> to fix this.
