I noticed that
static void uart_flush_buffer(struct tty_struct *tty)
{
struct uart_state *state = tty->driver_data;
struct uart_port *port = state->port;
unsigned long flags;/*
* This means you called this function _after_ the port was
* closed. No cookie for you.
*/
if (!state || !state->info) {
WARN_ON(1);
return;
}is too late for checking state != NULL.

mpc52xx_uart_int and __uart_put_char both try to acquire the
port->lock. Therefore the function sequence of:mpc52xx_uart_int--> ...-->flush_to_ldisc-->...-->__uart_put_char
can potentially trigger a deadlock. To avoid this deadlock a fix
similar to that found in the 8250.c serial driver is applied. The
deadlock is avoided by releasing the lock before pushing a buffer
and reacquiring it when completed.Signed-off-by: Andrew Liu

- Stop drivers calling their own flush method indirectly, it obfuscates code
and it will change soon anyway- A few more lock_kernel paths temporarily needed in some driver internal
waiting code- Remove private put_char method that does a write call for one char - we
have that anyway- Most but not yet all of the termios copy under lock fixing (some has other
dependencies to follow)- Note a few locking bugs in drivers found in the process
- Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to

Thomas Koeller had reported an issue where a device that had been making use
of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by
the backup timer test, causing the device to work improperly.To fix this, tighten the test requirements to enable the backup timer
workaround.The backup timer is really meant to catch UARTs that don't re-assert the THRE
interrupt. The expectation is that they do initially assert THRE. This patch
clarifies the test.Signed-off-by: Alex Williamson

We try and write the correct speed back but the serial midlayer already
