Subject: [PATCH 3/5] orinoco: simplify locking, fix error handling in PCMCIA resume
Date: Mon, 01 May 2006 02:13:28 -0400 [thread overview]
Message-ID: <20060501061328.13342.20411.stgit@dv.roinet.com> (raw)
In-Reply-To: <20060501061324.13342.58195.stgit@dv.roinet.com>
From: Pavel Roskin <proski@gnu.org>
Don't use flags in the spinlocks - the PCMCIA resume functions may not
be called under lock. Don't ignore any errors.
