From 0825d54a3081151201bbfe05f4d408613ef3ef1e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?N=C3=ADcolas=20F=2E=20R=2E=20A=2E=20Prado?= Date: Tue, 20 Jun 2023 18:08:25 -0400 Subject: [PATCH] kselftest/alsa: pcm-test: Move stream duration and margin to variables MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The duration to stream for and time margin to consider the stream failed are currently hardcoded values. Move them to variables so they can be reused and more easily changed. Signed-off-by: Nícolas F. R. A.
