2016-11-18cxl: Fix error handling in _cxl_pci_associate_default_context()Christophe Jaillet
'cxl_dev_context_init()' returns an error pointer in case of error, not NULL. So test it with IS_ERR.

2016-07-14cxl: Allow a default context to be associated with an external pci_devIan Munsie
The cxl kernel API has a concept of a default context associated with each PCI device under the virtual PHB. The Mellanox CX4 will also use the cxl kernel API, but it does not use a virtual PHB - rather, the AFU appears as a physical function as a peer to the networking functions. In order to allow the kernel API to work with those networking functions, we will need to associate a default context with them as well. To this end, refactor the corresponding code to do this in vphb.c and export it so that it can be called from the PHB code.
