## Description

In the Linux kernel, the following vulnerability has been resolved:  thermal/drivers/hisi: Drop second sensor hi3660  The commit 74c8e6bffbe1 ("driver core: Add __alloc_size hint to devm allocators") exposes a panic "BRK handler: Fatal exception" on the hi3660_thermal_probe funciton. This is because the function allocates memory for only one sensors array entry, but tries to fill up a second one.  Fix this by removing the unneeded second access.
