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.

5a54d4161a drivers: Fix build for Linux v6.12 
In Linux v6.12 the definition 'no_llseek' was finally removed. Since
Linux v6.0 it had been redefined as NULL. Add a test to conftest to
determine if 'no_llseek' is present and if not then it is no longer
necessary to populate this and we can leave as NULL.

ce678a37b1 drivers: Add conftest test for class_create 
In Linux v6.4, the module pointer argument is removed from the
class_create() function. Add a test to the conftest script that checks
if this argument for the class_create() function has been removed and
use the definition created by conftest to select which version of the
function is used.

4be2dd36bb nvidia-oot: remove module * from class_create() 
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.
