Subject: [PATCH] Fix bogus avdtp error codes management
Date: Mon, 17 Sep 2007 19:41:21 +0200	[thread overview]
Message-ID: <46EEBC41.80401@silicom.fr> (raw)

Hi Johan & Marcel,

While trying to fix this cross case issue, i came with an issue with the 
way error codes are handled
in avdtp.c.
The issue is basically that the part of the code that retrieves the 
exact error value is never executed
due to premature return.

Please have a look at the current patch.

Fabien
