Ensure that the take argument is a valid bucket ID before indexing the
buckets array.

We were indexing the buckets array without verifying the index was
within the [0,max_buckets) range. This could happen because
a multistep rule does not have enough buckets and has CRUSH_ITEM_NONE
for an intermediate result, which would feed in CRUSH_ITEM_NONE and
make us crash.

In ALSA timer core, the active timer instance is managed in
active_list linked list. Each element is added / removed dynamically
at timer start, stop and in timer interrupt. The problem is that
snd_timer_interrupt() has a thinko and leaves the element in
active_list when it's the last opened element. This eventually leads
to list corruption or use-after-free error.
This hasn't been revealed because we used to delete the list forcibly
in snd_timer_stop() in the past. However, the recent fix avoids the
double-stop behavior (in commit [f784beb75c: ALSA: timer: Fix link
corruption due to double start or stop]), and this leak hits reality.
This patch fixes the link management in snd_timer_interrupt(). Now it
simply unlinks no matter which stream is.

changeset 70433a152f ("media: videobuf2: Refactor vb2_fileio_data
and vb2_thread") broke videobuf2-dvb.
The root cause is that, instead of calling threadio->fnc() for
all types of events except for VB2_BUF_STATE_ERROR, it was calling
it only for VB2_BUF_STATE_DONE.
With that, the DVB thread were never called.

The vb2_thread implementation was made generic and was moved from
videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately
that clearly was never tested since it broke read() causing NULL address
references.
The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb
pointer in various core functions).
The v4l2_buffer no longer exists after moving the code into the core and
it is no longer needed. However, the vb2_thread code passed a pointer to
a vb2_buffer to the core functions were a v4l2_buffer pointer was expected
and vb2_thread expected that the vb2_buffer fields would be filled in
correctly.
This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the
pb pointer is a void pointer, so no type-checking took place.
This patch fixes this problem:
1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use
a NULL pointer here since they don't care about v4l2_buffer anyway.
2) let vb2_core_dqbuf pass back the index of the received buffer. This is
all vb2_thread needs: this index is the index into the q->bufs array
and vb2_thread just gets the vb2_buffer from there.
3) the fileio->b pointer (that originally contained a v4l2_buffer) is
removed altogether since it is no longer needed.
Tested with vivid and the cobalt driver.

The tda1004x was updating the properties cache before locking.
If the device is not locked, the data at the registers are just
random values with no real meaning.
This caused the driver to fail with libdvbv5, as such library
calls GET_PROPERTY from time to time, in order to return the
DVB stats.
