[PATCH] socket.c: fixed uninitialized fd->revents member in ssh_socket_poll() function

[Vic Lee <llyzs@xxxxxxx>]

Hi,

The attached patch is simple and self-explained. It applies to v0-4 branch.

Ths issue was actually quite serious. Intermittently it caused 
channel_select() enter in an infinite loop, took 100% CPU and never return.

Vic
