Subject: [PATCH V11 5/9] vfio: platform: add extra debug info argument to call reset
Date: Tue, 19 Jul 2016 09:01:45 -0400 [thread overview]
Message-ID: <1468933309-19735-6-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1468933309-19735-1-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.
