I'll have to find out another way of doing this. Amit

At init, qemu_chr_reset is always called with initial_reset_issued set to 1. So checking for it to be set is not necessary. A later patch will make use of initial_reset_issued to send the reset event only if the char device is opened instead of each time when qemu resets it Signed-off-by: Amit Shah <amit.shah@redhat.com> --- qemu-char.c | 5 ++--- 1 files changed, 2 insertions(+), 3 deletions(-)
