| |
Use sub-function of_compatible during probe, instead of using the node name. The code should not rely on the node names during probe, in addition to that the previously hard-coded node names are not compliant to the latest naming convention (they are not generic and they use underscores), and it was broken by mistake already once [1].
[1] commit 56086b5e804f ("ARM: dts: imx6qdl-apalis: Avoid underscore in node name")
