Subject: gpio: modify sysfs gpio export so that "value" displays as 0 or 1
From: "Steven A. Falco" <sfalco@xxxxxxxxxx>
gpiolib can export GPIOs to userspace via sysfs. This patch modifies the
gpio_value_show() so that any non-zero value is explicitly printed as "1",
rather than whatever numerical value the lower-level driver returns.
