[ Upstream commit 8700ce07c5c6bf27afa7b59a8d9cf58d783a7d5c ]

Fix error handling in cc_map_hash_request_update where sg_nents_for_len
return value was assigned to u32, converting negative errors to large
positive values before passing to sg_copy_to_buffer.

Check sg_nents_for_len return value and propagate errors before
assigning to areq_ctx->in_nents.

The heuristics used by gcc triggers false positive truncation
warnings in hifn_alg_alloc.  The warning triggered by the strings
here are clearly false positives (see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95755).

Add checks on snprintf calls to silence these warnings, including
the one for cra_driver_name even though it does not currently trigger
a gcc warning.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

xts_check_key() is obsoleted by xts_verify_key(). Over time XTS crypto
drivers adopted the newer xts_verify_key() variant, but xts_check_key()
is still used by a number of drivers. Switch drivers to use the newer
xts_verify_key() and make a couple of cleanups. This allows us to drop
xts_check_key() completely and avoid redundancy.

This driver has been implicitly relying on kmalloc alignment
to be sufficient for DMA.  This may no longer be the case with
upcoming arm64 changes.

This patch changes it to explicitly request DMA alignment from
the Crypto API.

ccree_init() calls cc_debugfs_global_fini(), the former is an init
function and the latter an exit function though.

A modular build emits:

	WARNING: modpost: drivers/crypto/ccree/ccree.o: section mismatch in reference: init_module (section: .init.text) -> cc_debugfs_global_fini (section: .exit.text)

(with CONFIG_DEBUG_SECTION_MISMATCH=y).
