Since commit f9a8ee8c8b ("pwm: Always allocate PWM chip base ID
dynamically") the value held in base isn't used any more in the PWM
framework. All PMWs get assigned a dynamic ID, so the assignment is
redundant and can be dropped.

====================
Mellanox shared branch that includes:
* Removal of FPGA TLS code https://lore.kernel.org/all/cover.1649073691.git.leonro@nvidia.com
Mellanox INNOVA TLS cards are EOL in May, 2018 [1]. As such, the code
is unmaintained, untested and not in-use by any upstream/distro oriented
customers. In order to reduce code complexity, drop the kernel code,
clean build config options and delete useless kTLS vs. TLS separation.
[1] https://network.nvidia.com/related-docs/eol/LCR-000286.pdf
* Removal of FPGA IPsec code https://lore.kernel.org/all/cover.1649232994.git.leonro@nvidia.com
Together with FPGA TLS, the IPsec went to EOL state in the November of
2019 [1]. Exactly like FPGA TLS, no active customers exist for this
upstream code and all the complexity around that area can be deleted.

The internal recvmsg() functions have two parameters 'flags' and 'noblock'
that were merged inside skb_recv_datagram(). As a follow up patch to commit
f4b41f062c ("net: remove noblock parameter from skb_recv_datagram()")
this patch removes the separate 'noblock' parameter for recvmsg().
Analogue to the referenced patch for skb_recv_datagram() the 'flags' and
'noblock' parameters are unnecessarily split up with e.g.
err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT,
flags & ~MSG_DONTWAIT, &addr_len);
or in
err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg,
sk, msg, size, flags & MSG_DONTWAIT,
flags & ~MSG_DONTWAIT, &addr_len);
instead of simply using only flags all the time and check for MSG_DONTWAIT
where needed (to preserve for the formerly separated no(n)block condition).

A CPU will not show up in virtualized environment which includes an

bring up a CPU and this CPU will remain in CPU_UP_PREPARE state.
The kernel will wait up to ten seconds for CPU to show up (do_boot_cpu())
and then rollback the hotplug state back to CPUHP_OFFLINE leaving the CPU
state in CPU_UP_PREPARE. The CPU state is set back to CPUHP_TEARDOWN_CPU
during the CPU_POST_DEAD stage.
After the Enclave VM terminates, the primary VM can bring up the CPU
again.

The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature. Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().
This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.

This is a small helper function to handle the error path more easily
when an error happens during the probe for the device with the
device-managed card. Since devres releases in the reverser order of
the creations, usually snd_card_free() gets called at the last in the
probe error path unless it already reached snd_card_register() calls.
Due to this nature, when a driver expects the resource releases in
card->private_free, this might be called too lately.
As a workaround, one should call the probe like:
static int __some_probe(...) { // do real probe.... }
static int some_probe(...)
{
return snd_card_free_on_error(dev, __some_probe(dev, ...));
}
so that the snd_card_free() is called explicitly at the beginning of
the error path from the probe.
This function will be used in the upcoming fixes to address the
regressions by devres usages.
