Subject: [PATCH 05/17] media: camss: csid-170: don't enable unused irqs
Date: Tue, 11 May 2021 14:07:12 -0400	[thread overview]
Message-ID: <20210511180728.23781-6-jonathan@marek.ca> (raw)
In-Reply-To: <20210511180728.23781-1-jonathan@marek.ca>

csid_isr() only checks for the reset irq, so enabling any other irqs
doesn't make sense. The "RDI irq" comment is also wrong, the register
should be CSID_CSI2_RDIN_IRQ_MASK. Without this fix there may be an
excessive amount of irqs.
