Re: HDMI field order

I was discussing this with Tim earlier, and there was a little confusion. He meant V4L2_FIELD_SEQ_TB/BT, not V4L2_FIELD_INTERLACED. When I tried out 1080i50 with HDMI in and the i.MX6, I got something that looks like V4L2_FIELD_SEQ_TB. The question though is: are the field rows always

[PATCH] dvb_frontend: don't use-after-free the frontend struct

dvb_frontend_invoke_release() may free the frontend struct. So, the free logic can't update it anymore after calling it. That's OK, as __dvb_frontend_free() is called only when the krefs are zeroed, so nobody is using it anymore. That should fix the following KASAN error: The KASAN report looks
