The strcpy() function has been deprecated and replaced with strscpy().
This patch shall replace it in the whole USB tree.

If hugetlb_cma_only is enabled, we know that hugetlb pages
can only be allocated from CMA. Now that there is an interface
to do early reservations from a CMA area (returning memblock
memory), it can be used to allocate hugetlb pages from CMA.
This also allows for doing pre-HVO on these pages (if e
