Subject: [PATCH] Incorrect revents in polypaudio plugin
Date: Tue, 07 Mar 2006 18:19:24 +0100	[thread overview]
Message-ID: <440DC09C.5080102@cendio.se> (raw)

[-- Attachment #1: Type: text/plain, Size: 183 bytes --]

The revent flags POLLIN/POLLOUT got switched in the Polypaudio plugin. 
Most applications check both so it went unnoticed until now.

Signed-off-by: Pierre Ossman <ossman@cendio.se>
