An IO address, tagged with __iomem, is passed to debugfs_create_file
as private data. This requires that it be cast to void *. The cast
creates a sparse warning:
/scratch/dja/linux-capi/drivers/misc/cxl/debugfs.c:51:57: warning: cast removes
address space of expression
The address space marker is added back in the file operations
(fops_io_u64).
Silence the warning with __force.
