Then, it may clear\ntz->debugfs after one of those functions has checked it and the\nstruct thermal_debugfs object may be freed prematurely.\n\nTo address the first problem, pass a pointer to the thermal zone's\nstruct thermal_debugfs object to debugfs_create_file() in\nthermal_debug_tz_add() and make tze_seq_start(), tze_seq_next(),\ntze_seq_stop(), and tze_seq_show() retrieve it from s->private\ninstead of a pointer to the thermal zone object.  This will ensure\nthat tz_debugfs will be valid across the \"mitigations\" file accesses\nuntil thermal_debugfs_remove_id() called by thermal_debug_tz_remove()\nremoves that file.\n\nTo address the second problem, use tz->lock in thermal_debug_tz_remove()\naround the tz->debugfs value check (in case the same thermal zone is\nremoved at the same time in two different threads) and its reset to NULL.\n\nCc :6.8+ <stable@vger.kernel.org> # 6.8+"
