This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 63781394c540dd9e666a6b21d70b64dd52bce76e ]
request_any_context_irq() returns a negative value on failure.
It returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED on success.
So fix testing return value of request_any_context_irq().
Also fixup the return value of devm_request_any_context_irq() to make it
consistent with request_any_context_irq().
Fixes: 0668d3065128 ("genirq: Add devm_request_any_context_irq()")
