From 688004a6acf7d1d568a660546816a092b6cc32ed Mon Sep 17 00:00:00 2001 From: "MONTANARO Luciano (MM)" Date: Tue, 4 Mar 2014 12:51:36 +0100 Subject: [PATCH] pcm: Wrap hw_ptr to boundary in pcm_ioplug The function snd_pcm_ioplug_hw_ptr_update() always increased the hw_ptr by delta, without wrapping it to the boundary. This would lead to problems when after many hours, the hw_ptr would overflow.
