Pull power management fixes from Rafael Wysocki:
 "These fix a crash in intel_pstate during resume from suspend-to-RAM
  that may occur after recent changes and two resource leaks in error
  paths in the operating performance points (OPP) framework, add a new
  C-states table to intel_idle and update the cpuidle MAINTAINERS entry
  to cover the governors too.

  Specifics:

   - Fix recently introduced crash in the intel_pstate driver that
     occurs if scale-invariance is disabled during resume from
     suspend-to-RAM due to inconsistent changes of APERF or MPERF MSR
     values made by the platform firmware (Rafael Wysocki).

   - Fix a memory leak and add a missing clk_put() in error paths in the
     OPP framework (Quanyang Wang, Viresh Kumar).

   - Add new C-states table for SnowRidge processors to the intel_idle
     driver (Artem Bityutskiy).

   - Update the MAINTAINERS entry for cpuidle to make it clear that the
     governors are covered by it too (Lukas Bulwahn)"

Pull SCSI fixes from James Bottomley:
 "This is a load of driver fixes (12 ufs, 1 mpt3sas, 1 cxgbi).

  The big core two fixes are for power management ("block: Do not accept
  any requests while suspended" and "block: Fix a race in the runtime
  power management code") which finally sorts out the resume problems
  we've occasionally been having.

  To make the resume fix, there are seven necessary precursors which
  effectively renames REQ_PREEMPT to REQ_PM, so every "special" request
  in block is automatically a power management exempt one.

  All of the non-PM preempt cases are removed except for the one in the
  SCSI Parallel Interface (spi) domain validation which is a genuine
  case where we have to run requests at high priority to validate the
  bus so this becomes an autopm get/put protected request"

Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville
platforms.

The following has been changed.

 1. C1E latency changed from 10us to 15us. It was measured using the
    open source "wult" tool (the "nic" method, 15us is the 99.99th
    percentile).

 2. C1E power break even changed from 20us to 25us, which may result
    in less C1E residency in some workloads.

 3. C6 latency changed from 50us to 130us. Measured the same way as C1E.

The C6 C-state is supported only by some SnowRidge revisions, so add a C-state
table commentary about this.

On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of
the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even
though C6 is present in the table, the driver will only use it if the CPU does
support it.

When sugov_update_single_perf() falls back to the "frequency"
path due to the missing scale-invariance, it will call
cpufreq_driver_fast_switch() via sugov_fast_switch()
and the driver's ->fast_switch() callback will be invoked,
so it must not be NULL.

However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement
the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to
NULL when it is going to use intel_cpufreq_adjust_perf(), which is a
mistake, because on x86 the scale-invariance may be turned off
dynamically, so modify it to retain the original ->adjust_perf()
callback pointer.

  Revert "dm crypt: export sysfs of kcryptd workqueue"

This reverts commit a2b8b2d975673b1a50ab0bcce5d146b9335edfad.

WQ_SYSFS breaks the ability to reload a DM table due to sysfs kobject
collision (due to active and inactive table). Given lack of
demonstrated need for exposing this workqueue via sysfs: revert
exposing it.

Fix the clock reference counting by calling the missing clk_put() in the
error path.

Cc: v5.10 <stable@vger.kernel.org> # v5.10
Fixes: dd461cd9183f ("opp: Allow dev_pm_opp_get_opp_table() to return -EPROBE_DEFER")
Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>

In function _allocate_opp_table, opp_dev is allocated and referenced
by opp_table via _add_opp_dev. But in the case that the subsequent calls
return -EPROBE_DEFER, it will jump to err label and opp_table will be
freed. Then opp_dev becomes an unreferenced object to cause memory leak.
So let's call _remove_opp_dev to do the cleanup.

This fixes the following kmemleak report:

unreferenced object 0xffff000801524a00 (size 128):
