This leads to a compile error :

Do you compile atmel_serial as module? I compiled built-in and it was fine
for me.
So the function should be exported like mctrl_gpio_to_gpiod() I guess.
An other reason can be you have CONFIG_GPIOLIB=n ?
In fact, mctrl_gpio_is_gpio() should depend on CONFIG_GPIOLIB for empty
body.
well, I'm also compiling it built-in (I even have config_module=N)
You have no CONFIG_GPIOLIB enabled and it is the bug in the patchset.
Thanks.

kernel is 3.19-rc3 with your patches ontop.
I attached my .config (saved as a defconfig)
arm-linux-gcc (GCC) 4.7.3
