drivers/net/wireless/hostap: Integer overflow
The local variable 'value' comes from 'extra', a parameter of function
'prism2_ioctl_priv_prism2_param'. If a large number passed to 'value',
there would be an integer overflow in the following line:
local->passive_scan_timer.expires = jiffies +
local->passive_scan_interval * HZ
