[Qemu-commits] [COMMIT 4460712] Fix struct termios host - target translation |

From: Arnaud Patard <address@hidden>
When converting the termios structure between host and target in
target_to_host_termios and host_to_target_termios, the c_cc[] array is
never initialised.
Calling memset() before using it allows to run successfully "stty echo /
stty -echo" on arm-linux-user target (host being x86 and mips).
