I noticed the patches for f71862fg support in f71808e driver are still
missing in the recent pull request. This might be due to the ioctl
implementation 	(PATCHv3 2/3) mentioned above which wasn't clarified.
Since i missed to reply at your remarks this was my fault. Now i hope
the PATCHv3 1/3 and 3/3 to get through as they already were signed-off
by the author of that driver. Since the patch in question isn't
essential for driver operation i suggest to drop that issue.
Sorry for the inconvenience.

With kind regards,

Lutz Ballaschke
