Subject: [PATCH V9 5/9] vfio: platform: add extra debug info argument to call reset
Date: Wed, 13 Jul 2016 22:06:31 -0400	[thread overview]
Message-ID: <1468461995-32676-6-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1468461995-32676-1-git-send-email-okaya@codeaurora.org>

Getting ready to bring out extra debug information to the caller
so that more verbose information can be printed when an error is
observed.
