commit b75ca5217743e4d7076cf65e044e88389e44318d upstream.

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready.

Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized.

Hence replace setup_irq() by request_irq().
