Merge tag 'ntb-4.13-bugfixes' of git://github.com/jonmason/ntb
Pull NTB fixes from Jon Mason:
"NTB bug fixes to address an incorrect ntb_mw_count reference in the
NTB transport, improperly bringing down the link if SPADs are
corrupted, and an out-of-order issue regarding link negotiation and
data passing"
* tag 'ntb-4.13-bugfixes' of git://github.com/jonmason/ntb:
ntb: ntb_test: ensure the link is up before trying to configure the mws
ntb: transport shouldn't disable link due to bogus values in SPADs
ntb: use correct mw_count function in ntb_tool and ntb_transport
