2020-06-30IB/hfi1: Convert PCIBIOS_* errors to generic -E* errorsBolarinwa Olayemi Saheed
pcie_speeds() and restore_pci_variables() returns PCIBIOS_ error codes from PCIe capability accessors. PCIBIOS_ error codes have positive values. Passing on these values is inconsistent with functions which return only a negative value on failure. Before passing on the return value of PCIe capability accessors, call pcibios_err_to_errno() to convert any positive PCIBIOS_ error codes to negative generic error values.

2020-06-24IB/mad: Issue complete whenever decrements agent refcountShay Drory
Replace calls of atomic_dec() to mad_agent_priv->refcount with calls to deref_mad_agent() in order to issue complete. Most likely the refcount is > 1 at these points, but it is difficult to prove. Performance is not important on these paths, so be obviously correct.

It's easy to show that sdev and req are always valid. So we remove unnecessary WARN_ON.

Commit 130f4caf145c ("libata: Ensure ata_port probe has completed before detach") may cause system freeze during suspend. Using async_synchronize_full() in PM callbacks is wrong, since async callbacks that are already scheduled may wait for not-yet-scheduled callbacks, causes a circular dependency. Instead of using big hammer like async_synchronize_full(), use async cookie to make sure port probe are synced, without affecting other scheduled PM callbacks.

2020-06-17nvdimm/region: always show the 'align' attributeVishal Verma
It is possible that a platform that is capable of 'namespace labels' comes up without the labels properly initialized. In this case, the region's 'align' attribute is hidden. Howerver, once the user does initialize he labels, the 'align' attribute still stays hidden, which is unexpected. The sysfs_update_group() API is meant to address this, and could be called during region probe, but it has entanglements with the device 'lockdep_mutex'. Therefore, simply make the 'align' attribute always visible. It doesn't matter what it says for label-less namespaces, since it is not possible to change their allocation anyway.
