From 0dea0141a9d9c33a669c546f8f5d9f44a0557375 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 28 Mar 2012 11:48:42 +0200 Subject: [PATCH] Bluetooth: vhci: Ignore return code of nonseekable_open() The comment in ./fs/open.c clearly states that nonseekable_open() will never fail. Therefore, we can safely ignore the return code. This is the recommended way to deal with nonseekable_open(). Our current code looks like nonseekable_open() is checked for the return code. However, if we check the return code, we must also kfree() our private data if the open fails. To avoid this overhead and to avoid confusion, we simply drop the return code and return 0.
