2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Hans Verkuil <hans.verk...@cisco.com> [ upstream commit 227690df75382e46a4f6ea1bbc5df855a674b47f ] g/s_tuner The subdevs are supposed to receive a valid tuner type for the g_frequency and g/s_tuner subdev ops. Some drivers do this, others don't. So prefill this in v4l2-ioctl.c based on whether the device node from which this is called is a radio node or not. The spec does not require applications to fill in the type, and if they leave it at 0 then the 'check_mode' call in tuner-core.c will return an error and the ioctl does nothing.
