.. which isn't in the master branch of git.linuxtv.org/sailus/media_tree.git
I've now taken Linus' tree of today, merged in char-misc-next, merged in
the media_tree, and applied a fixup patch (see bottom of the message).
Booting this kernel, there is no WARNING during boot, and I can suspend and
resume. However, please note the warnings/failures and the long delays
between suspend entry and exit during the first (two) suspend/resume cycles:
