Subject: net_sched: fix a missing idr_remove() in u32_delete_key()
From: Cong Wang <xiyou.wangcong@xxxxxxxxx>
[ Upstream commit f12c643209db0626f2f54780d86bb93bfa7a9c2d ]
When we delete a u32 key via u32_delete_key(), we forget to
call idr_remove() to remove its handle from IDR.
Fixes: e7614370d6f0 ("net_sched: use idr to allocate u32 filter handles")
