gpio: tegra186: Set affinity callback to parent (c4e1f7d9) · Commits · 戴 / test

This assigns the .irq_set_affinity to the parent callback. I assume the Tegra186 is an SMP system so this would be beneficial. I used the pattern making the hirerarchy tolerant for missing parent as in Marc's earlier patch. Suggested-by:
