From 149709f5b8a4a8678401facb5c670119751f6087 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 13 Jan 2012 11:46:36 -0200 Subject: [PATCH] [media] dvb-core: preserve the delivery system at cache clear The changeset 240ab508aa is incomplete, as the first thing that happens at cache clear is to do a memset with 0 to the cache. So, the delivery system needs to be explicitly preserved there.
