The patch titled Subject: acpi_memhotplug.c: free memory device if acpi_memory_enable_device() failed has been removed from the -mm tree. Its filename was acpi_memhotplugc-free-memory-device-if-acpi_memory_enable_device-failed.patch This patch was dropped because other changes were merged, which wrecked this patch ------------------------------------------------------ From: Wen Congyang <wency@xxxxxxxxxxxxxx> Subject: acpi_memhotplug.c: free memory device if acpi_memory_enable_device() failed If acpi_memory_enable_device() fails, acpi_memory_enable_device() will return a non-zero value, which means we fail to bind the memory device to this driver. So we should free memory device before acpi_memory_device_add() returns.
