thermal/drivers/hisi: Drop second sensor hi3660

Published Sep 15, 2025 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
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.
