[PATCH] pinctrl: aw9523: allow building as loadable module

[PATCH] pinctrl: aw9523: allow building as loadable module

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_I2C is set to =m, the new aw9523 driver fails to link:

arm-linux-gnueabi-ld: drivers/pinctrl/pinctrl-aw9523.o: in function `aw9523_probe':
pinctrl-aw9523.c:(.text+0x9f8): undefined reference to `__devm_regmap_init_i2c'
arm-linux-gnueabi-ld: drivers/pinctrl/pinctrl-aw9523.o: in function `aw9523_driver_init':
pinctrl-aw9523.c:(.init.text+0x4): undefined reference to `i2c_register_driver'
arm-linux-gnueabi-ld: drivers/pinctrl/pinctrl-aw9523.o: in function `aw9523_driver_exit':
pinctrl-aw9523.c:(.exit.text+0x2): undefined reference to `i2c_del_driver'

Make it a tristate symbol so the dependency is correctly honored.

I sent something similar yesterday:

Thanks anyway!
