This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Don't populate the read-only arrays sha256_init, sha224_init, sha1_init
and md5_init on the stack at run time, instead make them static.

In the EIP93 HASH functions, the eip93_put_descriptor is called without
acquiring lock. This is problematic when multiple thread execute hash
operations.
Correctly acquire ring write lock on calling eip93_put_descriptor to
prevent concurrent access and mess with the ring pointers.

Add support for the Inside Secure SafeXcel EIP-93 Crypto Engine used on
Mediatek MT7621 SoC and new Airoha SoC.
EIP-93 IP supports AES/DES/3DES ciphers in ECB/CBC and CTR modes as well as
authenc(HMAC(x), cipher(y)) using HMAC MD5, SHA1, SHA224 and SHA256.
EIP-93 provide regs to signal support for specific chipers and the
driver dynamically register only the supported one by the chip.
