func.inc.php: get_host_summary() fails on "devs" API command

[spamkit]

Sometimes Anubis displays no stats and displays device count as 0/0. This is caused by bug in cgminer forming invalid JSON when issuing "devs" command. The invalid part of JSON is "MHS 5s":-nan. This "-nan" is causing the trouble.

How to fix:

• patch func.inc.php:
• - find function send_request_to_host($cmd_array, $host_data).
• - replace $line = add_quotes_to_numbers($line); with $line = preg_replace("/("MHS\s_\w+":)(-_nan)/", '${1}0', add_quotes_to_numbers($line));

Have fun!
