Subject: input/binary: align sr_session_send() chunks to unit size
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=cb0fedd942ce286eb77de4dd1e3f981566f6ab6d;p=libsigrok.git

input/binary: align sr_session_send() chunks to unit size

The input/binary module chops raw input data into chunks and sends these
to the session feed. The total size of input chunks got aligned to the
unit size, the session feed output didn't. Make sure to align session
packets with the input data's unit size, too.

This fixes bug #1582.
