Subject: [PATCH] wistron_btns: Fix missing BIOS signature handling
Date: Sun, 08 Jan 2006 07:39:59 +0100	[thread overview]
Message-ID: <43C0B3BF.5050100@volny.cz> (raw)

[-- Attachment #1: Type: text/plain, Size: 160 bytes --]

offset can never be < 0 because it has type size_t.  The driver
currently oopses on insmod if BIOS does not support the interface,
instead of refusing to load.

[-- Attachment #2: wistron-no-entry.patch --]
[-- Type: text/x-patch, Size: 640 bytes --]

offset can never be < 0 because it has type size_t.  The driver
currently oopses on insmod if BIOS does not support the interface,
instead of refusing to load.
