In Linux v5.19, the arguments to the 'suspend' function pointer defined
in the structure 'ufs_hba_variant_ops' was updated to add a 'status'
argument. Add a new test to the conftest script that checks if the
'suspend' function has a 'status' argument and use the definition
created by conftest to select which structure member is used.
This is beneficial for working with 3rd party Linux kernels that may
have back-ported upstream changes into their kernel and so the kernel
version checks do not work.

Clean-up the UFS headers by adding a new top-level header for ufshcd.h,
ufshci.h and unipro.h that will include the appropriate header
depending on kernel version. This saves replicating the kernel version
check for every source file that includes these headers.
Note that the ufshcd-pltfrm.h header is identical between v5.15, v5.16
and 6.1 kernels and so remove the duplicated versions of this header and
just use a common header for all kernel versions.

In Linux v6.8, the 'g_frame_interval' function pointer was removed from
the 'v4l2_subdev_video_ops' structure and replaced by
'get_frame_interval' that was added to the 'v4l2_subdev_pad_ops'
structure. Add a test to conftest to detect if 'get_frame_interval' is
supported and update the camera CSI driver accordingly to populate the
appropriate function pointer.
Note that the new 'get_frame_interval' function pointer has an
additional 'state' argument but is otherwise the same as the previous
'g_frame_interval' function pointer.

Commit 54c86dd20bba ("pwm: Replace PWM chip unique base by unique ID")
removed the 'base' field of the 'pwm_chip' structure replacing it with
an 'id' field. The new 'id' is initialised by the PWM driver core and
does not need to be configured by the PWM drivers.
Add a test for conftest to detect if the 'pwm_chip' structure has the
'base' field and update the various PWM driver to only set this field if
present.

The earlier porting of the driver for Linux 6.6 is not
matching with the previous kernel implementation.
Few V4L2 APIs have been deprecated from Linux 6.6. and
added the new APIs.
Use the correct API available from Linux6.6 for the
replacement as the previous supported kernel APIs.
For reference, the changes in core kernels are:
The device argument is added in the API v4l2_async_nf_init() with
commit b8ec754ae4c5 ("media: v4l: async: Set v4l2_device and subdev

The API is removed with commit bda8953e8c3e ("media: v4l: async: Drop

Building nv_ar0234 and nv_hawk_owl sensor drivers with GCC 6/7 fails

drivers/media/i2c/nv_ar0234.c:797:66: error: initialiser element is not

These older versions of GCC are not able to reconcile the size from the
variable 'alternating_exposure_cfg_size' even though it is defined as
const. Given that the variable 'alternating_exposure_cfg_size' is only
used here, fix this by removing this variable and directly defining the
size in the declaration of the 'compound_ctrl_size' parameter.
Note that the minimum GCC compiler currently supported by the Linux
kernel is v5.1.

For Linux v6.8, support for SPI controllers with multiple chip-selects
was added to the SPI core and this updated the 'chip_select' member of
the 'spi_device' structure to be an array. This breaks building the
Tegra124 SPI Slave driver and Tegra210 QUAD SPI driver.
A helper function, spi_get_chipselect(), was added for Linux v6.3 to
retrieve the chip-select for a SPI device and can be used for retrieving
the chip-select for all Linux v6.3+ kernels.
Add a conftest rule to detecting if spi_get_chipselect() is present and
if so use this for getting the chip-select. This fixes the build issues
for Linux v6.8.

The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. The build failures occur because either the driver is missing
an include file which has the prototype or because the function is not
declared statically when it should be (ie. there are no external users).
Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.

The Tegra124 SPI slave driver declares a prototype for the function
tegra_spi_slave_register_callback() that does not exist. The correct
function name is tegra124_spi_slave_register_callback() and so fix the
prototype accordingly. Move the prototype to an actual header because
this is the correct place for defining prototypes for other drivers to
reference. This was caught by enabling the compiler flag
-Wmissing-prototype.
