Subject: DecodeSignal: avoid specifying a zero samplerate to libsigrokdecode
X-Git-Url: http://git.code-monkey.de/?a=commitdiff_plain;h=ba5b52e12e2d95c5ac9155cb697e002df5df1de6;hp=ba5b52e12e2d95c5ac9155cb697e002df5df1de6;p=pulseview.git

DecodeSignal: avoid specifying a zero samplerate to libsigrokdecode

When the sample rate is not known, avoid claiming the value would be
zero and calling setup routines in backend libraries. Although the call
is not strictly fatal, this simple check avoids potential log messages
at callee's for this unexpected condition.
