Subject: [PATCH 2/9] IR: minor fixes:
Date: Thu, 29 Jul 2010 02:40:45 +0300	[thread overview]
Message-ID: <1280360452-8852-3-git-send-email-maximlevitsky@gmail.com> (raw)
In-Reply-To: <1280360452-8852-1-git-send-email-maximlevitsky@gmail.com>

* lirc: Don't propagate reset event to userspace
* lirc: Remove strange logic from lirc that would make first sample always be pulse
* Make TO_US macro actualy print what it should.
