Merge v7.2-rc1 into drm-rust-next to start the next cycle.

Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

crypto: sun8i-ss - Remove crypto_rng interface

Since the crypto_rng interface for hardware PRNGs is unused and is
redundant with hwrng and the actual Linux RNG, it's being phased out.
Most drivers for it were already removed. Go ahead and remove the
sun8i-ss support which is one of the only remaining ones.

As usual for crypto_rng, this driver was also buggy: its ->generate()
function had a use-after-free vulnerability due to using
wait_for_completion_interruptible_timeout() without handling shutting
down the DMA operation if a signal is sent. Also, it had a buffer
overread bug in the line 'memcpy(ctx->seed, d + dlen, ctx->slen);'.
There's no point in fixing these bugs separately only to remove the code
anyway, so this commit is marked with Fixes and Cc stable.

crypto: sun4i-ss - Remove insecure and unused rng_alg

Remove sun4i_ss_rng, as it is insecure and unused:

- It has multiple vulnerabilities. sun4i_ss_prng_seed() is missing
locking and has a buffer overflow. sun4i_ss_prng_generate() fails to
fill the entire buffer with cryptographic random bytes, because it
rounds the destination length down and also doesn't actually wait for
the hardware to be ready before pulling bytes from it.

- No user of this code is known. It's usable only theoretically via the
"rng" algorithm type of AF_ALG. But userspace actually just uses the
actual Linux RNG (/dev/random etc) instead. And rng_algs don't
contribute entropy to the actual Linux RNG either. (This may have
been confused with hwrng, which does contribute entropy.)

The sun4i_ss_prng_seed() buffer overflow was reported by Tianchu Chen
and discovered by Atuin - Automated Vulnerability Discovery Engine

There's no point in fixing all these vulnerabilities individually when
this is unused code, so let's just remove it.

crypto: sun8i-ss - avoid hash and rng references

While the sun4i-ss and sun8i-ce drivers started selecting CRYPTO_RNG,
the sun8i-ss variant does not, and causes a link failure:

aarch64-linux-ld: drivers/crypto/allwinner/sun8i-ss/sun8i-ss-core.o: in function `sun8i_ss_unregister_algs':
sun8i-ss-core.c:(.text.sun8i_ss_unregister_algs+0x94): undefined reference to `crypto_unregister_rng'
aarch64-linux-ld: drivers/crypto/allwinner/sun8i-ss/sun8i-ss-core.o: in function `sun8i_ss_probe':
sun8i-ss-core.c:(.text.sun8i_ss_probe+0x40c): undefined reference to `crypto_register_rng'

Looking more closely, I see that all of the allwinner crypto drivers have the
same logic where the rng and hash parts of the driver are optional, but then the
generic code is still selected, which is a bit inconsistent, aside from the
missing CRYPTO_RNG select on sun8i-ss.

Change the approach so only the bits that are actually used are built, using
ifdef checks around the optional portions that match the optional references
to the sub-drivers.

Ideally the drivers would get reworked in a way that keeps all the bits
related to the skcipher/ahash/rng codecs in the respective sub-drivers,
rather than having a common driver that knows about all of these.
