Title
platform/mellanox: mlxbf-pmc: add sysfs_attr_init() to count_clock init
Summary
In the Linux kernel, the following vulnerability has been resolved: platform/mellanox: mlxbf-pmc: add sysfs_attr_init() to count_clock init The lock-related debug logic (CONFIG_LOCK_STAT) in the kernel is noting the following warning when the BlueField-3 SOC is booted: BUG: key ffff00008a3402a8 has not been registered! ------------[ cut here ]------------ DEBUG_LOCKS_WARN_ON(1) WARNING: CPU: 4 PID: 592 at kernel/locking/lockdep.c:4801 lockdep_init_map_type+0x1d4/0x2a0 <snip> Call trace: lockdep_init_map_type+0x1d4/0x2a0 __kernfs_create_file+0x84/0x140 sysfs_add_file_mode_ns+0xcc/0x1cc internal_create_group+0x110/0x3d4 internal_create_groups.part.0+0x54/0xcc sysfs_create_groups+0x24/0x40 device_add+0x6e8/0x93c device_register+0x28/0x40 __hwmon_device_register+0x4b0/0x8a0 devm_hwmon_device_register_with_groups+0x7c/0xe0 mlxbf_pmc_probe+0x1e8/0x3e0 [mlxbf_pmc] platform_probe+0x70/0x110 The mlxbf_pmc driver must call sysfs_attr_init() during the initialization of the "count_clock" data structure to avoid this warning.
