File nagios-plugins-enhance_check_sensors.patch of Package nagios-plugins

If you look closely at what check_sensors is doing, it has a
not-so-sophisticated series of "if" statements that tries to hit a proper case
as reported by runnings the "sensors(1)" command.  

But it's missing a very important conditional. The script presumes that a
non-error condition will return an RC of 0, and that all error cases will
return an RC > 0.  The important case that is missed is that 0 is returned if
the kernel module isn't loaded.
