Would you mind joining Mauro and I in #v4l on irc.freenode.net ?
We would just like to discuss the situation with your patches and
whether the v4l patch depends on the dvb counterpart, etc.... Whether or
not it is safe for me to send the dvb portion of the patch to akpm, or
if Mauro should ask akpm to drop the v4l portion until it can get more
We both will be in #v4l today, as we are both regularly found in that
chat room. If not today, then tomorrow or the next day..... OR, just
email us back to let us know the status, but a quick chat would be nice.
