From 645d64a5b0ab2eae42c1280029ad2b13e7509308 Mon Sep 17 00:00:00 2001 From: Joe Lawrence Date: Thu, 30 Apr 2015 17:16:04 +0300 Subject: xhci: gracefully handle xhci_irq dead device commit 948fa13504f80b9765d2b753691ab94c83a10341 upstream. If the xHCI host controller has died (ie, device removed) or suffered other serious fatal error (STS_FATAL), then xhci_irq should handle this condition with IRQ_HANDLED instead of -ESHUTDOWN.
