Sorry, but this is still broken.

Those tags need to come before the "---". Otherwise they will not
end-up into the actual commit when this patch is applied.

It should look something like this:

        usb: typec: qcom-pmic: init value of hdr_len/txbuf_len earlier

        If the read of USB_PDPHY_RX_ACKNOWLEDGE_REG failed, then hdr_len and
        txbuf_len are uninitialized. This commit stops to print uninitialized
        value and misleading/false data.
