[PATCH] Char: mxser_new, alter locking in isr
Avoid oopsing when stress-testing open/close -- port->tty is NULL sometimes,
but is expected to be non-NULL, since dereferencing. Receive/transmit chars
iff ASYNC_CLOSING is not set and ASYNC_INITIALIZED is set. Thanks Sergei for
pointing this out and testing.
