Upon receipt of SYNACK from the server, ipt_SYNPROXY first sends back an ACK to
finish the server handshake, then calls nf_ct_seqadj_init() to initiate
sequence number adjustment of forwarded packets to the client and finally sends
a window update to the client to unblock it's TX queue.
Since synproxy_send_client_ack() does not set synproxy_send_tcp()'s nfct
parameter, no sequence number adjustment happens and the client receives the
window update with incorrect sequence number. Depending on client TCP
implementation, this leads to a significant delay (until a window probe is
being sent).

Commit 77a3c6fd90 ("[media] vb2: Don't WARN when v4l2_buffer.bytesused
is 0 for multiplanar buffers") uses the __WARN() macro which isn't
defined when CONFIG_BUG isn't set. This introduces a compilation
breakage. Fix it by using WARN_ON() instead.
The commit was also broken in that it merged v1 of the patch while a new
v2 version had been submitted, reviewed and acked. Fix it by
incorporating the changes from v1 to v2.

Currently micd_dbtime can be set to 0 for default, 1 for 4 measurements,
or a greater than 16-bit value for 2 measurements. This patch simplifies
the symantics to 2 for 2 measurements, 4 for 4 measurements and any
other value for the default.
I am not super keen on changing the symantics of the pdata at this stage
in the drivers life, but acceptance of the DT binding for this field has
been made conditional on this happening.

Detecting an open-circuit on the microphone pin, usually means the
headset has a microphone but the cable is faulty. Currently the code
will simply stop detecting and declare nothing in this situation. It is
better to declare this as headphones such that the user can still use
their headset as plain headphones even if the microphone is faulty.

MAX20751 is a multiphase power controller with internal buck converter.
It uses VR12.0 to report the output voltage. This requires an explicit

If type = f71858fg/f8000/f81866a. the temp_start will set to 0,
others are 1.
The F81866 over-temperature beep setting is not the same with
f71882fg too. They are using the same address 63H, but F81866 is
using bit 0/1/2 & 4/5/6, others are using bit 1/2/3 & 5/6/7,
