It seems to fix the issue, but I do not see any way to fix this just for mxs-auart.c without also changing serial_core.h, and thus affecting a bunch of other drivers. Would reverting the changes from 2d141e683e9a ("tty: serial: use uart_port_tx() helper") for just mxs-auart.c be okay? If so, I can do that, test it again, and send a patch. -- Emil
