Description
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: llcc: Handle a second device without data corruption Usually there is only one llcc device. But if there were a second, even a failed probe call would modify the global drv_data pointer. So check if drv_data is valid before overwriting it.
