Subject: [PATCH v3 2/3] pwm: Add can_sleep property to drivers
Date: Mon, 28 Jan 2013 15:00:58 +0100 [thread overview]
Message-ID: <1359381659-24454-3-git-send-email-florian.vaussard@epfl.ch> (raw)
In-Reply-To: <1359381659-24454-1-git-send-email-florian.vaussard@epfl.ch>
Calls to PWM drivers connected through I2C can sleep.
Use the new can_sleep property.
