Merge tag 'thermal-v6.10-rc1-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Merge thermal driver fixes for 6.10-rc1 from Daniel Lezcano:

"- Check for a NULL pointer before using it in the probe routine of the
   Mediatek LVTS driver (Julien Panis)

 - Remove the num_lvts_sensor and cal_offset fields of the
   lvts_ctrl_data as they are not used. These are not functional fixes
   but slight memory usage fix of the Mediatek LVTS driver (Julien
   Panis)

 - Fix wrong lvts_ctrl index leading to a NULL pointer dereference in
   the Mediatek LVTS driver (Julien Panis)"
