[PATCH 0/4][T] CVE-2016-7913 - Use-after-free in XCeive xc2028 tuner driver

https://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-7913.html

 It was discovered that a use-after-free vulnerability existed in the device
 driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local
 attacker could use this to cause a denial of service (system crash) or
 possibly execute arbitrary code.

Patches 2, 3, and 4 are requird to address CVE-2016-7913. I believe that patch
1 is a pre-req in order to get the error handling of xc2028_set_config()
correct before it can properly handle the error condition addressed in the CVE
fix. I don't have a way to test these patches since I don't have the tuner
hardware.

This issue only needs to be patched in Trusty.
