Subject: fix type of internally used sframes variable, to avoid unnecessary casts
X-Git-Tag: v1.0.17a~5
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=15769ead725b7c215dedd4ea5196955086d2044a;p=alsa-lib.git

fix type of internally used sframes variable, to avoid unnecessary casts

This minor patch fixes the type of the sframes variable in
snd_pcm_plugin_forward(). With this fix we need to cast less and the
code is less confusing.
