在 Linux 内核中，已修复以下漏洞：
EDAC/igen6: 修复因缺少 release() 函数导致的调用跟踪（call trace）问题。
当卸载 igen6_edac 驱动程序时，会出现如下调用跟踪信息：
``` Device '(null)' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst. WARNING: drivers/base/core.c:2567 at device_release+0x84/0x90, CPU#5: rmmod/127209 ... RIP: 0010:device_release+0x84/0x90 Call Trace: <TASK> kobject_put+0x8c/0x220 put_device+0x17/0x30 igen6_unregister_mcis+0xa2/0xe0 [igen6_edac]
igen6_remove+0x82/0xb0 [igen6_edac]
... ```
通过为内存控制器设备提供空的 release() 函数来修复该调用跟踪问题。
