Subject: [PATCH] HID: mcp2221: add gpiolib dependency
Without gpiolib, this driver fails to link:
arm-linux-gnueabi-ld: drivers/hid/hid-mcp2221.o: in function `mcp2221_probe':
hid-mcp2221.c:(.text+0x1b0): undefined reference to `devm_gpiochip_add_data'
arm-linux-gnueabi-ld: drivers/hid/hid-mcp2221.o: in function `mcp_gpio_get':
hid-mcp2221.c:(.text+0x30c): undefined reference to `gpiochip_get_data'
Fixes: 328de1c519c5 ("HID: mcp2221: add GPIO functionality support")
