This is the second attempt at moving priority handling into the core. I have added two helper functions that allocate and free just a single v4l2_fh struct. This can be used by drivers that do not need to embed the struct v4l2_fh into a larger struct. It is also called by the core for any driver that does not supply open() or release() callbacks in struct v4l2_file_operations. This replaces the awkward 'store priority in private_data' hack from the previous patch series. This means that almost all radio devices automatically support priority handling (since most do not supply open/release). This patch series also converts radio-mr800 (removing the bogus autopm support allows us to remove the open/release support) and radio-cadet (typical first-time open and close code, shows how easy it is to use the helper functions). ivtv is also converted as it is currently the only driver that embeds struct v4l2_fh. Core support for priority handling is necessary in order to have consistent handling of priorities and to handle priorities and the control framework. A lot of video drivers do something in open and/or release, so it is quite a bit of work to implement this. However, the changes needed to convert a driver are trivial and are easy to review.
