Kevin Wolf 2c8a59422c char: Fix return type of qemu_chr_fe_add_watch() ... qemu_chr_fe_add_watch() can return negative errors, therefore it must not have an unsigned return type. For consistency with other qemu_chr_fe_* functions, this uses a standard C int instead of glib types. In situations where qemu_chr_fe_add_watch() is falsely assumed to have succeeded, the serial ports would go into a state where it never becomes ready for transmitting more data; this is fixed by this patch.
