This is a layering violation so we replace it with calls to
sg_page. This is a prep patch for replacing page_link and this
is one of the very few uses outside of scatterlist.h.

"gcc -Wunused" warns about one argument being assigned but not used:
drivers/staging/ccree/ssi_cipher.c: In function 'ssi_blkcipher_complete':
drivers/staging/ccree/ssi_cipher.c:747:41: error: parameter 'info' set but not used [-Werror=unused-but-set-parameter]
We can simply drop that argument here and in its callers.

Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element
Semantic patch information:
This makes an effort to find cases where ARRAY_SIZE can be used such as
where there is a division of sizeof the array by the sizeof its first
element or by any indexed element or the element type. It replaces the
division of the two sizeofs by ARRAY_SIZE.
