Subject: [PATCH v3 1/2] gpio: moxart: Avoid forward declaration
Date: Tue, 25 Mar 2014 10:43:33 +0800	[thread overview]
Message-ID: <1395715413.12999.0.camel@phoenix> (raw)

Slightly adjust the code to avoid forward declaration as we need to call
moxart_gpio_set() in moxart_gpio_direction_output() to properly set the
output state.
