Subject: Rename 'probe' to 'channel' everywhere.
X-Git-Tag: libsigrokdecode-0.3.0~33
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=6a15597a7b3f901b566b7bfc8c484a14e0fb6a11;p=libsigrokdecode.git

Rename 'probe' to 'channel' everywhere.

Variables of type 'struct srd_channel *' are consistently named 'pdch' to
make them easily distinguishable from libsigrok's 'struct sr_channel *'
variables that are consistently named 'ch'.
