That's not true, it's "tristate" in drivers/net/wan/Kconfig so it
could be set to 'y' too.

But there is another reason to make this change, because for such
large timeout values only msleep() makes sense, udelay() could
overflow it's internal precision.

Please resubmit this with the proper reasoning and commit message.
