Description
In the Linux kernel, the following vulnerability has been resolved:

spi: uniphier: Fix completion initialization order before devm_request_irq()

The driver calls devm_request_irq() before initializing the completion
used by the interrupt handler. Because the interrupt may occur immediately
after devm_request_irq(), the handler may execute before init_completion().

This may result in calling complete() on an uninitialized completion,
causing undefined behavior. This has been observed with KASAN.

Fix this by initializing the completion before registering the IRQ.
