PCI: keystone: Use ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW to get interrupt status
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. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
