From feb836992437c9b8b53988da30880e0e6e93ac8b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 24 Oct 2011 15:24:10 +0200 Subject: gpiolib: Ensure struct gpio is always defined Currently struct gpio is only defined when using gpiolib which makes the stub gpio_request_array() much less useful in drivers than is ideal as they can't work with struct gpio. Since there are no other definitions in kernel instead make the define always available no matter if gpiolib is selectable or selected, ensuring that drivers can always use the type.
