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.

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.

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.
