Subject: [PATCH AUTOSEL 5.15 01/23] firmware: dmi: Use the proper accessor for the version field
Date: Tue, 30 Aug 2022 13:21:18 -0400 [thread overview]
Message-ID: <20220830172141.581086-1-sashal@kernel.org> (raw)
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
[ Upstream commit d2139dfca361a1f5bfc4d4a23455b1a409a69cd4 ]
The byte at offset 6 represents length. Don't take it and drop it
immediately by using proper accessor, i.e. get_unaligned_be24().
[JD: Change the subject to something less frightening]
