Subject: devlink: drop the filter argument from devlinks_xa_find_get
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8861c0933c78e3631fe752feadc0d2a6e5eab1e1;p=linux.git

devlink: drop the filter argument from devlinks_xa_find_get

Looks like devlinks_xa_find_get() was intended to get the mark
from the @filter argument. It doesn't actually use @filter, passing
DEVLINK_REGISTERED to xa_find_fn() directly. Walking marks other
than registered is unlikely so drop @filter argument completely.
