diff --git a/drivers/acpi/acpi_mrrm.c b/drivers/acpi/acpi_mrrm.c index 2f22f013959a..70088cdfde13 100644 --- a/drivers/acpi/acpi_mrrm.c +++ b/drivers/acpi/acpi_mrrm.c @@ -156,8 +156,10 @@ static __init int add_boot_memory_ranges(void) for (int i = 0; i < mrrm_mem_entry_num; i++) { name = kasprintf(GFP_KERNEL, "range%d", i); - if (!name) + if (!name) { + ret = -ENOMEM; break; + } kobj = kobject_create_and_add(name, pkobj);
The error code is not set correctly on if kasprintf() fails. On the first iteration it would return -EINVAL and subsequent iterations would return success. Set it to -ENOMEM. In real life, this allocation will not fail and if it did the system will not boot so this change is mostly to silence static checker warnings more than anything else.
