@masayuki2009 Thanks for your comment, regarding: > Furthermore, in cxd56_serial.c case, I remember that up_txint() is called recursively. In this case, if we apply the driver-specific spinlock it would also cause a deadlock. I think this recursion is only there because of the SUPPRESS_SERIAL_INTS part, where I believe an else is missing. In normal cases (where we don't suppress serial interrupts) we should just enable interrupts and leave. This shouldn't recurse. -- This is an automated message from the Apache Git Service.
