Wang Liang 955f400e4f net: atm: fix memory leak in atm_register_sysfs when device_register fail ... [ Upstream commit 0a228624bcc00af41f281a2a84c928595a74c17d ] When device_register() return error in atm_register_sysfs(), which can be triggered by kzalloc fail in device_private_init() or other reasons, kmemleak reports the following memory leaks: unreferenced object 0xffff88810182fb80 (size 8): comm "insmod", pid 504, jiffies 4294852464 hex dump (first 8 bytes): 61 64 75 6d 6d 79 30 00 adummy0. backtrace (crc 14dfadaf): __kmalloc_node_track_caller_noprof+0x335/0x450 kvasprintf+0xb3/0x130 kobject_set_name_vargs+0x45/0x120 dev_set_name+0xa9/0xe0 atm_register_sysfs+0xf3/0x220 atm_dev_register+0x40b/0x780 0xffffffffa000b089 do_one_initcall+0x89/0x300 do_init_module+0x27b/0x7d0 load_module+0x54cd/0x5ff0 init_module_from_file+0xe4/0x150 idempotent_init_module+0x32c/0x610 __x64_sys_finit_module+0xbd/0x120 do_syscall_64+0xa8/0x270 entry_SYSCALL_64_after_hwframe+0x77/0x7f When device_create_file() return error in atm_register_sysfs(), the same issue also can be triggered. Function put_device() should be called to release kobj->name memory and other device resource, instead of kfree().
