Uwe Kleine-König f0ef883cae soc: qcom: llcc: Handle a second device without data corruption 
[ Upstream commit f1a1bc8775 ]

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.
