To modify the global seqno may require rewriting a few registers, which

This commit makes transfer function use spi_transfer_is_last to
determine if currently processed transfer is the last one. Thanks to
that we finally set hardware registers properly and it makes controller
behave the way it's expected to.
This allows simplifying read function which can now simply start reading
from the slot 0 instead of the last saved offset. It has been
successfully tested using spi_write_then_read.
Moreover this change fixes handling messages with two writing transfers.
It's important for SPI flash devices as their drivers commonly use one
transfer for a command and another one for data.

This driver creates various const structures that it stores in the
data field of an of_device_id array.
Adding const to the declaration of the location that receives the
const value from the data field ensures that the compiler will
continue to check that the value is not modified. Furthermore, the
const-discarding cast on the extraction from the data field is no
longer needed.

Various Cherry Trail boards with a rt5645 codec have an analog mic
connected to IN2P + IN2N. The mic on this boards also needs micbias to
be enabled, on some boards micbias1 is used and on others micbias2, so
we enable both.
This commit adds a new "Int Analog Mic" DAPM widget for this, so that we
do not end up enabling micbias on boards with a digital mic which uses
the already present "Int Mic" widget. Some existing UCM files already
refer to "Int Mic" for their "Internal Analog Microphones" SectionDevice,
but these don't work anyways since they enable the RECMIX BST1 Switch
instead of the BST2 switch.

The GPD pocket has a differential signal microphone and needs in2_diff
to be set to avoid getting a very noisy signal.
Since the GPD pocket and win use the same DMI strings, they share their
platform data-definition, so enabling in2_diff on the pocket also sets
it on the GPD win. The GPD win has a normal microphone, but setting
in2_diff there does not negatively impact the sound from the microphone.

There's a logic at the VB2 core that produces a WARN_ON if
there are still buffers waiting to be filled. However, it doesn't
indicate what buffers are still opened, with makes harder to
identify issues inside caller drivers.
So, add a new pr_warn() pointing to such buffers. That, together
with debug instrumentation inside the drivers can make easier to
identify where the problem is.

Currently, there's a logic with checks if *count is non-zero,
q->num_buffers is zero and q->memory is different than memory.
That's flawed when the device is initialized, or after the
queues are freed, as it does, unnecessary calls to
__vb2_queue_cancel() and __vb2_queue_free().
That can be avoided by making sure that q->memory is set to
VB2_MEMORY_UNKNOWN at vb2_core_queue_init(), and adding such
check at the loop.

specified in the field defines (FSTV0910_*) in stv0910_regs.h, which was
recently updated to carry the missing offset values. With that, add the
SET_FIELD(), SET_REG() and GET_REG() macros that wrap the write_field(),
write_reg() and read_reg() functions to allow for making all demod
access code cleaner.
The write_field() function is annotated with __maybe_unused temporarily
