Subject: spi: cope when a sample rate of 0 was configured
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=956721de58552b05776c8613449f2907196e61e9

spi: cope when a sample rate of 0 was configured

The explicit test for None was not good enough. Change test conditions
such that sample rates only get processed when they got specified _and_
were not zero.

This fixes bug #1118.
