Subject: [PATCH] sensors-detect: Fix use of uninitialized value 'vendor_id' on
 ppc64

Based on a report and an original patch from Jaromir Capik:

There's no vendor_id entry in the /proc/cpuinfo file in case of PPC64
systems and consequently the script returns 3 screens full of the
following errors:

Use of uninitialized value in string eq at /usr/sbin/sensors-detect
line 6444
Use of uninitialized value in string eq at /usr/sbin/sensors-detect
line 6459
Use of uninitialized value in string eq at /usr/sbin/sensors-detect
line 6473
