Subject: [PATCH v2 2/3] pwm: Add can_sleep property to drivers
Date: Fri, 25 Jan 2013 14:44:30 +0100	[thread overview]
Message-ID: <1359121471-21457-3-git-send-email-florian.vaussard@epfl.ch> (raw)
In-Reply-To: <1359121471-21457-1-git-send-email-florian.vaussard@epfl.ch>

Calls to PWM drivers connected through I2C can sleep.
Use the new can_sleep property.
