From: Chandrakanth Patil <chandrakanth.patil@xxxxxxxxxxxx> commit 07d3f04550023395bbf34b99ec7e00fc50d9859f upstream. As the ENABLE_IRQ_POLL macro is undefined, the check for ENABLE_IRQ_POLL macro in ISR will always be false. This leads to irq polling being non-functional. Remove ENABLE_IRQ_POLL check from ISR.
