In success case, the revision holds a non-null pointer. The current logic incorrectly returns an error for a non-null pointer, whereas it should return an error for a null pointer. The socinfo driver for IPQ9574 and IPQ5332 is currently broken, resulting in the following error message qcom-socinfo qcom-socinfo: probe with driver qcom-socinfo failed with error -12 Add a null check for the revision to ensure it returns an error only in failure case (null pointer).
