ARM: PL011: Ensure IRQs are disabled in UART interrupt handler As the DMA support introduces a separate interrupt-time callback, our interrupt handler will not be the only handler which takes the port lock, so we need to ensure that IRQs are disabled. We must use the _irqsave variant so we don't inadvertently enable interrupts. Acked-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
