Yongqiang Liu 3cdd91a916 cpufreq: Init completion before kobject_init_and_add() ... commit 5c51054896bcce1d33d39fead2af73fec24f40b6 upstream. In cpufreq_policy_alloc(), it will call uninitialed completion in cpufreq_sysfs_release() when kobject_init_and_add() fails. And that will cause a crash such as the following page fault in complete: BUG: unable to handle page fault for address: fffffffffffffff8 [..] RIP: 0010:complete+0x98/0x1f0 [..] Call Trace: kobject_put+0x1be/0x4c0 cpufreq_online.cold+0xee/0x1fd cpufreq_add_dev+0x183/0x1e0 subsys_interface_register+0x3f5/0x4e0 cpufreq_register_driver+0x3b7/0x670 acpi_cpufreq_init+0x56c/0x1000 [acpi_cpufreq] do_one_initcall+0x13d/0x780 do_init_module+0x1c3/0x630 load_module+0x6e67/0x73b0 __do_sys_finit_module+0x181/0x240 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd Fixes: 4ebe36c94a ("cpufreq: Fix kobject memleak") Signed-off-by: Yongqiang Liu <liuyongqiang13@huawei.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: 5.2+ <stable@vger.kernel.org> # 5.2+ Signed-off-by: Rafael J.
