Hi Mauro,
These are the locking patches. It's based on my previous test tree, but with
more testing with em28xx and radio-mr800 and some small tweaks relating to
disconnect handling and video_is_registered().
I also removed the unused get_unmapped_area file op and I am now blocking
any further (unlocked_)ioctl calls after the device node is unregistered.
The only things an application can do legally after a disconnect is unmap()
and close().
This patch series also contains a small em28xx fix that I found while testing
the em28xx BKL removal patch.
Regards,
Hans
