Subject: [PATCH 1/1] crypto: ux500: hash: Add namespacing to hash_init()
A recent change to the Regulator consumer API (which this driver
utilises) add prototypes for the some suspend functions. These
functions require including header file include/linux/suspend.h.
The following tree of includes affecting this driver will be
present:
In file included from include/linux/elevator.h:6,
from include/linux/blkdev.h:288,
from include/linux/blk-cgroup.h:23,
from include/linux/writeback.h:14,
from include/linux/memcontrol.h:22,
from include/linux/swap.h:9,
from include/linux/suspend.h:5,
from include/linux/regulator/consumer.h:35,
from drivers/crypto/ux500/hash/hash_core.c:28:
include/linux/elevator.h pulls in include/linux/hashtable.h which
contains its own version of hash_init(). This confuses the build
system and results in the following error (amongst others):
drivers/crypto/ux500/hash/hash_core.c:1362:19: error: passing argument 1 of '__hash_init' from incompatible pointer type [-Werror=incompatible-pointer-types]
1362 | return hash_init(req);
Fix this by namespacing the local hash_init() such that the
source of confusion is removed.

Ideally this should go into v5.8's -rcs else it runs the risk of
breaking when Linus pulls everything in for v5.9-rc1.
