[PATCH] net: phy: spi_ks8995: add dependency on GPIO

[Sudip Mukherjee]

The builds of allmodconfig of s390, m68k, tilegx, tilepro is failing
with the error:
 drivers/net/phy/spi_ks8995.c:477:3: error: implicit declaration of function 'gpiod_set_value'
 drivers/net/phy/spi_ks8995.c:477:19: error: implicit declaration of function 'gpio_to_desc'

GPIO is now used to reset the switch so we should have a dependency on
GPIOLIB.

You're definitely right! This somehow slipped through, sorry for that!

Does that file include include/linux/gpio/consumer.h?
The GPIO subsystem provides dummies of these functions when CONFIG_GPIOLIB=n.

I think that can become

    depends on SPI
    depends on GPIOLIB || COMPILE_TEST

after you've added the missing include.

yes, ofcourse. Better change that what I have done. Just sent v2 after 
compile testing this change.
