In Linux v6.12, commit 88a2f6468d01 ("struct fd: representation change")
removed the 'struct file' pointer from 'struct fd'. This breaks building
the NVSCIIPC driver that tries to directly access the 'file' pointer
from the 'fd' structure. Fix this by using the helper macros 'fd_empty'
and 'fd_file' as necessary to fix the build.

For Linux v6.11, the 'pci_epc_event_ops' structure 'core_init' callback
was renamed to 'epc_init' and a new 'epc_deinit' callback was added.
Update the PCI endpoint drivers for Linux v6.11 by:
1. Adding tests to conftest to detect the presence of 'epc_init' and
'epc_deinit'.
2. Update the drivers as necessary to use the appropriate callback
depending upon what is present in the kernel.

Only Tegra234+ devices are currently supported and for these devices the
only DMA drivers that are supported for Linux are the Tegra210 ADMA and
Tegra186 GPCDMA drivers. Neither of these drivers ever supported the
'slave_id' parameter for configuring the DMA request ID for a given
channel. These drivers have always used device-tree to retrieve this
information. Only the Tegra20 APBDMA controller supported the 'slave_id'
field and this was dropped in Linux v5.17. The Tegra20 APBDMA driver was
supported in Tegra devices up until Tegra210, but starting with Tegra186
it is no longer supported.
Given that this is a legacy feature only supported for legacy Tegra
devices and drivers, drop the 'slave_id' support completely.

If the Linux kernel driver OPTEE is built as a module (CONFIG_OPTEE=m)
then building the MODS driver for Tegra fails with the following error
...
drivers/misc/mods/mods_optee.c:22:5:
error: no previous prototype for 'esc_mods_invoke_optee_ta'
[-Werror=missing-prototypes]
22 | int esc_mods_invoke_optee_ta(struct mods_client *client,

The problem is in the mods_internal.h file that wraps the prototype for
the above function with '#ifdef CONFIG_OPTEE'. This works fine for when
CONFIG_OPTEE=y but not if CONFIG_OPTEE=m. To ensure that this prototype
is present when the OPTEE driver is built into the kernel or a module,
we need to use '#if IS_ENABLED(CONFIG_OPTEE)'. Update the MODS driver
accordingly to fix this.

In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and
this breaks building some of the out-of-tree drivers for Linux v6.2+
kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks
building some of the out-of-tree drivers that use these legacy APIs. For
now the broken drivers are not built for these corresponding kernels.
Instead of checking the kernel version in the Makefile for the
corresponding broken driver, move the kernel version checking to the
top-level Makefile and add CONFIG definitions that can be used the
various Makefiles.
This is also needed for working with 3rd party Linux kernels that may
have upstream backports and need to set these CONFIG variables for their
Linux kernel.

The MODULE_IMPORT_NS macro adds a namespace tag to the module
information. The DMA_BUF namespace is required for Linux v5.16+ kernels
for drivers that use DMA BUF, there is no reason not to populate this
for earlier kernels. Furthermore, some 3rd party kernels prior to v5.16
may require this too and so drop the version check around the DMA BUF
namespace.

Remove the module pointer from the class_create() based
on following change in core kernel
======
driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something. So just remove it and fix up all callers of the function in
the kernel tree at the same time.
