Re: [PATCH] Implement V4L2_CAP_STREAMING for zr364xx driver

[Antoine Jacquet <royale@zerezo.com>]

Hi,

Sorry for the very late answer, I did not have time to work on my driver 
during the past months.
I managed to apply your patch to my current hg tree, but since it is 5 
months out of sync with the main tree, I am having issues to merge your 
work.
Could you send a patch against the current main tree ( 
http://linuxtv.org/hg/v4l-dvb/ ) so I can test your patch?

Thanks a lot and sorry again.

Regards,

Antoine
