Something like: > > +static int airoha_npu_reserve_mem_region(struct device *dev, > + struct resource *res) [...] Hi Lorenzo, Thanks for the review. Sure, I will move both into airoha_npu_reserve_mem_region() in v1. The pool attach then moves ahead of dma_set_mask_and_coherent(), which is fine since nothing allocates coherent memory in between. v1 will follow once net-next reopens, together with a binding fix from the Sashiko review of 1/3.
