Subject: [PATCH -next] mfd: tps6586x depends on GPIOLIB

From: Randy Dunlap <randy.dunlap@...cle.com>

tps6586x uses gpio interfaces, so it should depend on GPIOLIB.

Fixes these build errors:

drivers/mfd/tps6586x.c:41: error: field 'gpio' has incomplete type
drivers/mfd/tps6586x.c:195: warning: type defaults to 'int' in declaration of '__mptr'
drivers/mfd/tps6586x.c:195: warning: initialization from incompatible pointer type
drivers/mfd/tps6586x.c:210: warning: type defaults to 'int' in declaration of '__mptr'
drivers/mfd/tps6586x.c:210: warning: initialization from incompatible pointer type
drivers/mfd/tps6586x.c:219: warning: type defaults to 'int' in declaration of '__mptr'
drivers/mfd/tps6586x.c:219: warning: initialization from incompatible pointer type
drivers/mfd/tps6586x.c:249: error: implicit declaration of function 'gpiochip_add'
