Hans, I noticed a couple more issues with this series. In your changes to radio-mr800, you removed the lock from usb_amradio_suspend and usb_amradio_resume without implementing resume/suspend support in the v4l2 core. Without resume/suspend support in the v4l2 core, the locking within usb_amradio_suspend and usb_amradio_resume must remain to prevent races between other open/close/ioctl/read/mmap/etc and the resume/suspend cycle. Please revert the changes you made to these two functions.
