From 554713ee0a32cd8eabd75b276aeb82aa2570b030 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sat, 24 Oct 2020 23:23:07 +0200 Subject: azalia: Treat all negative return values as errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of checking whether the return value equals -1, just check if it is negative. Some Azalia implementations already do it, but most do not.
