Subject: [PATCH] x86/microcode/intel: Fix allocation size of struct ucode_patch
Date: Thu, 5 Jan 2017 01:03:51 +0000 [thread overview]
Message-ID: <7a730dc9-ac17-35c4-fe76-dfc94e5ecd95@ce.jp.nec.com> (raw)
We allocate struct ucode_patch here.
"size" is a size of microcode data and used for kmemdup() later
in this function.
Signed-off-by: Jun'ichi Nomura <j-nomura@ce.jp.nec.com>
Fixes: 06b8534cb728 ("x86/microcode: Rework microcode loading")
