[PATCH 1/6] crypto: eip93: return IRQ request errors from probe

[Jihong Min]

devm_request_threaded_irq() can fail, but eip93_crypto_probe()
continues as if the interrupt handler was installed. Return the error
immediately so the driver does not register algorithms for a device that
cannot signal completions.
