Descriptions

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.
