Subject: [PATCH 05/15] can: m_can: Disable unused interrupts
Date: Wed, 16 Nov 2022 21:52:58 +0100 [thread overview]
Message-ID: <20221116205308.2996556-6-msp@baylibre.com> (raw)
In-Reply-To: <20221116205308.2996556-1-msp@baylibre.com>
There are a number of interrupts that are not used by the driver at the
moment. Disable all of these.
