commit 128fdbf36cddc2a901c4889ba1c89fa9f2643f2c upstream.
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).

[ Upstream commit e694d2b5c58ba2d1e995d068707c8d966e7f5f2a ]
devm_kasprintf() can return a NULL pointer on failure but this
returned value in qcom_socinfo_probe() is not checked.
