[linux-dvb] Fwd: patch for support Leadtek Winfast DTV1800H

[Markus Rechberger]

Hi,

the v4l-dvb-experimental tree on mcentral.de isn't supposed to support
cx88/saa7134/xceive based devices, it's
only focussed on Empia based products before the development got split
out to em28xx-new. This was just a
sideeffect since those devices also used the available xceive driver back then.

Please apply your patch against the linuxtv.org code. this will save
you from incompatibility issues.
The v4l-dvb-experimental code hasn't got updated for a very long time
and lacks alot features now.

thanks,
Markus

Hi,

It is several months I send you my patch and it hasn't been merged
into repository yet.
Are there any problems with merging or do you manage the
v4l-dvb-kernel repository any more?

I'm also sending you a patch for kernel-2.6.24-git9 and later which
lacks 'usage_count'
in 'struct i2c_client'. (Do the older kernels need it?)

I look forward to your reply.
