 functions are compiled

3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Uwe Kleine-König <u.kleine-koenig@...gutronix.de>

commit 88003fb10f1fc606e1704611c62ceae95fd1d7da upstream.

This fixes a compile failure:

	drivers/built-in.o: In function `wm8350_i2c_probe':
	core.c:(.text+0x828b0): undefined reference to `__devm_regmap_init_i2c'
	Makefile:953: recipe for target 'vmlinux' failed

Fixes: 52b461b86a9f ("mfd: Add regmap cache support for wm8350")
