You also have to set 'err' if soc_version is 0, so the caller can skip
the check for soc_version == 0
I'd suggest:
// directly after setting soc_version
if (*soc_version == 0)
err = -EILSEQ; // or should it be a different error code?
...
if (err)
bt_dev_err(hdev, "QCA Failed to get version (%d)", err);
You could also limit the error log to the 'if (*soc_version == 0)'
branch, for all other errors there will already be a more specific log
entry.
