Subject: RE: linux-next: build failure after merge of the slave-dma tree

Hi Stephen,
	That's caused by 'of_irq_count' NOT export to global symbol, and I'm curious why it has been
here for so long since Zhangfei found it in 2015. https://patchwork.kernel.org/patch/7404681/
Hi Rob,
	Is there something I miss so that Zhangfei's patch not accepted finally?
