Subject: [PATCH v1 4/5] media: staging: tegra-vde: Do not handle spurious interrupts
Date: Sat, 17 Mar 2018 18:28:14 +0300	[thread overview]
Message-ID: <8d1b583bde182ab79a18f43df83f87affda6b174.1521300358.git.digetx@gmail.com> (raw)
In-Reply-To: <cover.1521300358.git.digetx@gmail.com>
In-Reply-To: <cover.1521300358.git.digetx@gmail.com>

Do not handle interrupts if we haven't asked for them, potentially that
could happen if HW wasn't programmed properly.
