[zhuguangqing83]

From: Guangqing Zhu <zhuguangqing83@gmail.com>

Fixes coccicheck error:

drivers/thermal/qcom/tsens.c:759:4-10: ERROR: missing put_device; call
of_find_device_by_node on line 715, but without a corresponding object
release within this function.

Fixes: a7ff82976122 ("drivers: thermal: tsens: Merge tsens-common.c into
tsens.c")
