It expects and initial value to be passed to gpio_direction_output() which has been introduced by commit 28735a7253a6c24364765e80a5428b4a151fccc2 in Linus git tree. Generic gpio layer is going to be used by pxa2xx_udc driver. Signed-off-by: Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
