f01227d4ea drivers: Drop inline from driver remove wrapper
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.

951b2423a8 drivers: Fix platform_driver remove for Linux v6.11
In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update all the impacted drivers
as necessary to fix this.

ab65399274 drivers: Fix missing headers for Linux v6.8
For Linux v6.8, commit ef175b29a242 ("of: Stop circularly including
of_device.h and of_platform.h") updated the OF headers included by these
header files. This breaks the build for various drivers and so fix this
by including the headers that are actually needed for each driver.

devm_tegra_core_dev_init_opp_table_common() is present in the kernel and
use the definition generated in the host1x driver.

63901a1066 drm/tegra: Enable runtime PM during probe
Currently, engine drivers only enable runtime PM during the host1x
init callback. This can happen slightly later than the probe, which
can cause the power domain to intermittently not be turned off after
probe.

My hypothesis is that there is a race condition between the post-probe
power domain poweroff that is done from a queued work, and the
pm_runtime_enable call happening in the host1x init callback.
If the pm_runtime_enable call happens first, everything is OK and
the power off work can disable the power domain as PM runtime is
enabled and the device is runtime suspended. If power off work runs
first, PM runtime is still disabled for the device and the domain
must be kept powered.

Resolve the issue by moving the runtime PM enablement to the
probe function.

b8c2d943ed drm/tegra: Add upstream tegra-drm driver
Add the upstream tegra-drm driver with the 'Host1x/Tegra UAPI' series
[0] applied. This driver will be built as an external module for testing
and development with upstream Linux kernels.

The following modifications have been made to the series posted upstream
1. Update the Makefile to always build the driver as a module
2. Always enable the tegra_drm_ioctl_xxx in the tegra_drm_ioctls and
   remove the dependency on CONFIG_DRM_TEGRA_STAGING.
3. Rename the include/uapi/drm/tegra_drm.h to
   include/uapi/drm/tegra_drm_next.h to avoid conflicts with upstream
   headers when building as an external module.
5. Rename the module that is built to be tegra-drm-next.ko instead of
   tegra-drm.ko to avoid any depmod conflicts with the upstream driver.
