Oops, sorry about that.

Thanks...

OK, I see.

I can do it for my tree but the branch already included in arm-soc tree so I think, it should be fixed with another patch. And

So how about following? If you are OK, let me take into samsung tree.

From: Kukjin Kim <kgene.kim@xxxxxxxxxxx>
Subject: [PATCH] ARM: SAMSUNG: change GENERIC_GPIO to ARCH_REQUIRE_GPIOLIB

When I applied regarding samsung-time patches, the "select GENERIC_GPIO"
has been added wrong, so this patch fixes that.
And since the GENERIC_GPIO in arch/arm/ will be gone away, this adds
ARCH_REQUIRE_GPIOLIB for S3C24XX and S5PC100 instead.
