Subject: [PATCH 06/18] can: m_can: Disable unused interrupts
Date: Wed, 21 Dec 2022 16:25:25 +0100 [thread overview]
Message-ID: <20221221152537.751564-7-msp@baylibre.com> (raw)
In-Reply-To: <20221221152537.751564-1-msp@baylibre.com>
There are a number of interrupts that are not used by the driver at the
moment. Disable all of these.
