Subject[PATCH net-next] sysfs: Fix regression when adding a file to an existing group
Date
Commit 5f81880d5204 ("sysfs, kobject: allow creating kobject belonging
to arbitrary users") incorrectly changed the argument passed as the
parent parameter when calling sysfs_add_file_mode_ns(). This caused some
sysfs attribute files to not be added correctly to certain groups.

Note, this was a regression exclusively in linux-next and never made it to
Linus' tree. There's no need to queue it up for linux-stable.
