The commit 512ae1bd6a ("perf tools: Consolidate management of default
sort orders") changed default value of the 'sort_order' variable to NULL
indicating that users don't set any sort keys on the command line.
However it missed to update a check in perf_evlist__tty_browse_hists()
so that 'perf report -T' cannot show the per-thread values after the
normal output. This patch fixes it to work again.
Note that the -T option only works on --stdio and neither --sort nor
--parent option was given.

Use the V4L2 core locking system instead of rolling your own. Switch to
the vb2 fop and ioctl helpers to get rid of a lot of code. This also made
it easy to add VB2_READ to the DMA modes, since you get read() for free
with vb2 and these helpers.
Finally remove the users field: this information is also available from

No controls were reported, even though the ov7670 does have controls.
Two reasons for this: the v4l2_ctrl_handler_init() call must come
before the ov7670 is loaded (otherwise the ov7670 won't know that
its controls should be added to the bridge driver), and the
v4l2_ctrl_handler_free() call at the end should only be called if
the ret value is non-zero (otherwise you would just free all the
controls that were just added).
