Subject: [PATCH v5 03/14] efi/apple-properties: use PROPERTY_ENTRY_U8_ARRAY_LEN
Date: Fri, 11 Oct 2019 16:07:10 -0700 [thread overview]
Message-ID: <20191011230721.206646-4-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20191011230721.206646-1-dmitry.torokhov@gmail.com>
Let's switch to using PROPERTY_ENTRY_U8_ARRAY_LEN() to initialize
property entries. Also, when dumping data, rely on local variables
instead of poking into the property entry structure directly.
