They fix race condition and null pointers dereference. I added the "stable" tag to each of them (v3.12). Even if we are late in the development cycle, can you please consider including these patches for 3.13? Thanks, best regards, Nicolas Ferre Marek Roszko (3): tty/serial: at91: Handle shutdown more safely tty/serial: at91: fix race condition in atmel_serial_remove tty/serial: at91: prevent null dereference in tasklet function Mark Deneen (1): tty/serial: at91: reset rx_ring when port is shutdown drivers/tty/serial/atmel_serial.c | 27 ++++++++++++++++++++++----- 1 file changed, 22 insertions(+), 5 deletions(-) -- 1.8.2.2
