Subject: [PATCH v2 18/21] PCI: keystone: Use ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW to get interrupt status
Date: Wed, 17 Oct 2018 13:11:11 +0530 [thread overview]
Message-ID: <20181017074114.28239-19-kishon@ti.com> (raw)
In-Reply-To: <20181017074114.28239-1-kishon@ti.com>
Use ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW to get interrupt
status. ERR_IRQ_STATUS_RAW has the status of the interrupts
before masking whereas ERR_IRQ_STATUS has the status of the interrupts
after masking. Since all the interrupts are unmasked here, use
ERR_IRQ_STATUS.
