From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dan Carpenter Date: Tue, 12 Jun 2012 16:28:50 +0000 Subject: [patch] ideapad: uninitialized data in ideapad_acpi_add() Message-Id: <20120612162850.GB11077@elgon.mountain> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Ike Panhc Cc: Matthew Garrett , platform-driver-x86@vger.kernel.org, kernel-janitors@vger.kernel.org We only initialize the high bits of "cfg". It probably doesn't cause a problem given that this is platform specific code and doesn't have to worry about endianness etc. But it's sort of messy.
