Subject: When detaching devices when we suspend, we need to continue processing
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5b24870b0b8fb52cfc1715886eaf8cb3e9fe99c6;p=openbsd

When detaching devices when we suspend, we need to continue processing
command completion events.  So only return early in xhci_softintr() if
the controller is dead instead of dying.  This fixes USB suspend/resume
in Apple M1/M2.
