Some distros might use old kernel source but with some latest upstream
kernel patches backported to their kernel source tree. To deal with this
scenario and avoid kernel compilation failure, use conftest to check the
existence of features against the kernel source tree which the OOT
modules are built upon and do the conditional build based on the test
result generated with the conftest tool.
Use NV_DEVFREQ_HAS_FREQ_TABLE to determine whether freq_table field is
there in struct devfreq data strcuture, and choose the correct path for
building the module.
Use tegra_wmark-specific devfreq_get_freq_range always to avoid kernel
version check and conftest check. Since devfreq_get_freq_range exists in
the devfreq-specific governor.h (e.g. drivers/devfreq/governor.h) file
instead of globabl linux kernel include header files
(e.g. include/linux/devfreq.h), conftest cannot be used to the existence
of devfreq_get_freq_range kernel function.

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.

In Linux v6.12, commit 8c045ca534d0 ("gpiolib: legacy: Kill GPIOF_DIR_*
definitions") removed the GPIOF_DIR_* definitions and updated drivers to
use the equivalent GPIOF_* definitions instead. The GPIOF_* definitions
were added in Linux v3.0 and so update the appropriate drivers to use
these definitions.
Note that when calling devm_gpio_request_one() with GPIOF_DIR_OUT for
the flags, then because no explicit output level is specified, the GPIO
driver core defaults to low. Hence, in this case we replace
GPIOF_DIR_OUT with GPIOF_OUT_INIT_LOW.

ISP channels are not released cleanly if the IVC send for
CAPTURE_CHANNEL_ISP_RELEASE_REQ were to fail, leaving the
rest of the release steps undone, including unregistering
the capture and control callbacks. This will prevent any
new channel setups, e.g., after an app restart, because
the channel is deemed busy.
Another problem with ISP channel release is that were the
aforementioned IVC sends to fail, the driver will not
attempt an RCE reboot to recover the IVC communications.
Similarly, if the channel reset IVC request fails or
returns an error, the pending capture and program buffers
won't be unpinned and their related waits won't be
completed.
This fix always performs the cleanups regardless of the
fate of the control channel requests.

nvmap uses pid of group_leader task to indicate a client process. During
create_client operation, whenever any client with the same group_leader
pid already exists in clients list of nvmap_device, then nvmap
increments the count field of nvmap_client struct. Otherwise, create a
new nvmap_client. Both of the operations i.e. checking the list for
client and incrementing the counter happen inside lock. On the other
hand, during nvmap_release, first the counter is decremented and checked
if it's zero or not. If it's zero then the lock is taken and client is
removed from client list of nvmap_device. As both the operations i.e.
decrementing the counter value and removing client from list (if the
counter becomes 0) are not happening inside a lock, it's resulting into
the following data race scenario.
1) nvmap_release on existing client process 1
- decrement client's counter
- counter value has become zero
- client is yet to be removed from the dev->clients list
- context switch happen to __nvmap_create_client as another
namespace/thread with same with same group_leader pid is created.
2) __nvmap_create_client
- as the client with same pid exists in dev->client list, it
increments counter value to 1, instead of creating a new client struct.
- context switch happen to nvmap_release from step 1
3) nvmap_release
- It calls destroy_client and remove the client from dev->client
list.
- Completes rest of the operations in destroy_client and returns.
- Context switch to remaining operations from step 2
4) nvmap_release
- Now, when the nvmap_release will be called for the thread/namespace
which was created in step 2, then list_del operation would fail as the
client struct was already removed from dev->client list.
Fix the above issue by doing both operations i.e. decrementing the
counter value and removing the client struct from dev->client list in a
single lock.

[Issue]: CAN freezes/stops to send messages after restart from bus-off state.
Throws following log from kernel: "write: No buffer space available"
[Reason]: When message txfer starts, tx_object (which keeps track of active tx)
gets filled. If CAN goes to bus-off state, txfer remains incomplete for some
messages. In such case, tx_object bits will not get cleared. It will stop
adding more messages in controller RAM.
Along with tx_object, from network layer, there are socket echo buffers.
When CAN is initialized and up on network, netif_start_queue is pushed to start
transmission. When msg txfer starts, socket buffer gets filled and freed only
when txfer completes. During bus-off, since network queue remains ON, all the
queued msgs get filled in socket buffers and does not allow upcoming msgs.
Therefore we see "write: No buffer space available".
[Fix]: Clear tx_object when device goes to bus-off state and stop network queue.
Start network queue again during restart from bus-off.
