Subject: [PATCH 02/17] media: camss: csiphy-3ph: disable interrupts
Date: Tue,  8 Jun 2021 18:34:51 -0400	[thread overview]
Message-ID: <20210608223513.23193-3-jonathan@marek.ca> (raw)
In-Reply-To: <20210608223513.23193-1-jonathan@marek.ca>

The driver does nothing with the interrupts, so set the irq mask registers
to zero to avoid wasting CPU time for nothing.
