I did the tracing and found that the ENOENT is coming from
sysfs_do_create_link_sd() in the following function call chain:
of_iommu_configure() -> iommu_probe_device() -> __iommu_probe_device() ->
iommu_init_device() -> iommu_device_link() -> sysfs_add_link_to_group() ->
sysfs_create_link_sd() -> sysfs_do_create_link_sd()
The particular block that emits the error is
static int sysfs_do_create_link_sd()
{
...
if (target_kobj->sd) {
target = target_kobj->sd;
kernfs_get(target);
}
if (!target)
return -ENOENT;
...
}
I believe that this is the same in the case that I am seeing as well.
