Subject: [PATCH 8/8] floppy: use warning macros
Date: Wed, 09 Jun 2010 11:34:57 -0700 [thread overview]
Message-ID: <20100609183626.499637581@vyatta.com> (raw)
In-Reply-To: 20100609183449.110905403@vyatta.com
[-- Attachment #1: floppy-warn.patch --]
[-- Type: text/plain, Size: 2215 bytes --]
Convert assertions to use WARN(). There are several error checks
in the code for things that should never happen. Convert them to
standard warnings so kerneloops.org will see them.
