…t 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 <[email protected]> Signed-off-by: Lorenzo Pieralisi <[email protected]>
