In Linux v6.8, the 'g_frame_interval' and 's_frame_interval' function
pointers were removed from the 'v4l2_subdev_video_ops' structure and
replaced by 'get_frame_interval' and 'set_frame_interval' that were
added to the 'v4l2_subdev_pad_ops' structure.
This change was previously fixed for the Tegra CSI driver by adding the
necessary conftest changes. A new update to the Tegra Cam V4L2 causes
the build to fail for Linux v6.8+ kernels because of the same issue. Fix
up the Tegra Cam V4L2 driver in the same way as the Tegra CSI driver,
but update the name of the conftest test to indicate that this is
applicable for both the 'get_frame_interval' and 'set_frame_interval'
function pointers.

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.

Upstream commit cdd9a571b7d8 ("fs/proc: move page_mapcount() to
fs/proc/internal.h") made page_mapcount() an internal function for Linux
v6.11. This function is used by the NVMAP driver and so implement this
function in the NVMAP driver directly instead. Note that newer kernels
implement folio_entire_mapcount() for compound page counts where as
older kernels use compound_mapcount(). Use conftest to detect which of
these functions is present in the kernel.

In Linux v6.11, commit d6f66e292676 ("pwm: Make pwm_request_from_chip()
private to the core") made the function pwm_request_from_chip() a
private function to the PWM core driver. This function is used by both
the CDI and ISC camera drivers and so these driver no longer build
against Linux v6.11.
Fix this by updating the CDI and ISC drivers to use the function
of_pwm_xlate_with_flags() which has been supported since Linux v3.8.
This function internally calls pwm_request_from_chip() and configures
the pwm->args.period parameter and is therefore, equivalent to the
existing code.

If CONFIG_V4L2_ASYNC is not enabled in the kernel, then the function
tegracam_v4l2subdev_register() will return -ENOTSUPP and this will cause
the probe of the sensor drivers to fail. Although failing to probe the
driver is expected in this case, it is not expected that this will
trigger a kernel panic if CONFIG_DEBUG_LIST is enabled. The panic is
caused because tegracam_device_unregister() is not being called in the
exit path of the probe function when tegracam_v4l2subdev_register()
returns an error.

The RealTek drivers do not build against all Linux distributions because
some Linux distributions have back-ported upstream changes and so the
KERNEL_VERSION checks in the driver do not work for these distributions.
Add compilation flags for these drivers so that we can skip the building
of these drivers for certain Linux distributions.
Please note that the RealTek drivers build fine against Linux v5.14 and
so we should not prevent these driver being built against all Linux
v5.14 kernels.
