Subject: input: accept const sdi in feed queue API
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=57140e5a804dd5b616120f05e38c3409241bb37c;p=libsigrok.git

input: accept const sdi in feed queue API

The common feed queue support code needs an sdi to submit sample data to
the session feed. Decorate this argument as const to silence compiler
warnings. This matches the sr_session_send() API.
