Revert "crypto: cavium/nitrox - add an error message to explain the failure of pci_request_mem_regions"

2021-05-13T15:23:05+00:00

This reverts commit 9fcddaf2e28d779cb946d23838ba6d50f299aa80 as it was
submitted under a fake name and we can not knowingly accept anonymous
contributions to the repository.

This commit was part of a submission "test" to the Linux kernel
community by some "researchers" at umn.edu.  As outlined at:
	https://www-users.cs.umn.edu/%7Ekjlu/papers/full-disclosure.pdf
it was done so as an attempt to submit a known-buggy patch to see if it
could get by our review.  However, the submission turned out to actually
be correct, and not have a bug in it as the author did not understand
how the PCI driver model works at all, and so the submission was
accepted.

As this change is of useless consequence, there is no loss of
functionality in reverting it.

 "This is a large update by KVM standards, including AMD PSP (Platform
  Security Processor, aka "AMD Secure Technology") and ARM CoreSight
  (debug and trace) changes.

  ARM:

   - CoreSight: Add support for ETE and TRBE

   - Stage-2 isolation for the host kernel when running in protected
     mode

   - Guest SVE support when running in nVHE mode

   - Force W^X hypervisor mappings in nVHE mode

   - ITS save/restore for guests using direct injection with GICv4.1

   - nVHE panics now produce readable backtraces

   - Guest support for PTP using the ptp_kvm driver

   - Performance improvements in the S2 fault handler

  x86:

   - AMD PSP driver changes

   - Optimizations and cleanup of nested SVM code

   - AMD: Support for virtual SPEC_CTRL

   - Optimizations of the new MMU code: fast invalidation, zap under
     read lock, enable/disably dirty page logging under read lock

   - /dev/kvm API for AMD SEV live migration (guest API coming soon)

   - support SEV virtual machines sharing the same encryption context

   - support SGX in virtual machines

   - add a few more statistics

   - improved directed yield heuristics

   - Lots and lots of cleanups

  Generic:

   - Rework of MMU notifier interface, simplifying and optimizing the
     architecture-specific code

   - a handful of "Get rid of oprofile leftovers" patches

   - Some selftests improvements"

crypto: s5p-sss - consistently use local 'dev' variable in probe()

2021-04-22T07:31:31+00:00

For code readability, the probe() function uses 'dev' variable instead
of '&pdev->dev', so update remaining places.

crypto: ccp - Make ccp_dev_suspend and ccp_dev_resume void functions

2021-04-22T07:31:31+00:00

Since ccp_dev_suspend() and ccp_dev_resume() only return 0 which causes
ret to equal 0 in sp_suspend and sp_resume, making the if condition
impossible to use. it might be a more appropriate fix to have these be
void functions and eliminate the if condition in sp_suspend() and
sp_resume().
