Since the legacy exporting is gone with 2f804aca4832 ("gpiolib:
Kill unused GPIOF_EXPORT and Co") there is no need to unexport
GPIO on freeing. Remove that call.

Note, the other users of this functionality do that explicitly,
except one SH and one OMAP boardfile which don't free GPIO anyways,
so it is safe to drop the call.

v2: mentioned OMAP boardfile as well

Ah, you already sent a v2. I applied this one.
