We will need this when we get the common routine working. thanks, -- Shuah

I actually folded it on the patch caching tuner and decoder, with is also needed for the common routine to work (as the core knows nothing about any au0828-specific caching). At the end of the day, we'll need to remove the cache as a hole, as we move the au0828_enable_source to the core.

As au0828 assumes that all links to ATV decoder and DTV demod should be disabled, make sure this is the case. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> --- drivers/media/usb/au0828/au0828-core.c | 19 +++++++++++-------- 1 file changed, 11 insertions(+), 8 deletions(-)
