Fix NetBSD CPU temp gauge bug
Patch status: merged
Patch by Alexander Vasarab
This patch fixes a bug in which multiple (conflicting) CPU temps may be included in the output for the "cpu temperature" module. The bug is due to the way that the code parsed the envsys(4)-returned data, and would manifest itself on x86-based NetBSD machines, since those use cputemp(4) as well as acpitz(4), thereby creating multiple envsys(4) entries with identical descriptions but which refer to different physical sensors. Instead of matching the description attribute of each device returned by envsys(4) against the target format, this patch throws away non-matching keys in the first instruction inside the dict walk. This has the benefit of sparing unnecessary CPU cycles, and preventing other sensors from being included erroneously. Additionally, the THERMAL_ZONE format is now joined with OpenBSD in that it uses acpitz(4) explicitly. This is prefered since it is much older (dating back to NetBSD 2.0), and does not exclude x86-based users (as with cputemp(4)).
