From: Hugo Villeneuve <hvilleneuve@dimonoff.com> Bit SRESET (3) is cleared when a reset operation is completed. Having the IOCONTROL register as non-volatile will always read SRESET as 1. Therefore mark IOCONTROL register as a volatile register. Signed-off-by: Hugo Villeneuve <hvilleneuve@dimonoff.com> --- drivers/tty/serial/sc16is7xx.c | 1 + 1 file changed, 1 insertion(+)
