Krzysztof Kozlowski 93b0beae72 pinctrl: samsung: Validate alias coming from DT ... Driver uses alias from Device Tree as an index of pin controller data array. In case of a wrong DTB or an out-of-tree DTB, the alias could be outside of this data array leading to out-of-bounds access. Depending on binary and memory layout, this could be handled properly (showing error like "samsung-pinctrl 3860000.pinctrl: driver data not available") or could lead to exceptions.
