[PATCH 3.14 29/64] xhci: gracefully handle xhci_irq dead device

Show all headers | View raw

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Joe Lawrence <joe.lawrence@stratus.com>

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.
