Subject: metex14: Use case-insensitive string compares.
X-Git-Tag: libsigrok-0.2.2~35
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=ee6cb5a417713a3080d03be44643b47131d59e2e

metex14: Use case-insensitive string compares.

This allows some other DMMs to be supported that use e.g. "kOhm" vs.
"KOhm", and so on.
