[Linux-stable-mirror] Stable patches for v4.14:dvb_frontend

Hi Greg,

please apply the following two patches to v4.14-stable.

62229de19ff2 media: dvb-core: always call invoke_release() in fe_free() b1cb7372fa82 dvb_frontend: don't use-after-free the frontend struct

The first patch fixes a bug and avoids a conflict when applying the second patch, and the second patch fixes CVE-2017-16648.

My apologies for the noise if the patches are already queued.

Thanks, Guenter
