Subject: [PATCH net-next] ieee802154: hwsim: fix rcu address annotation
Date: Tue, 7 Aug 2018 10:34:44 -0400 [thread overview]
Message-ID: <20180807143444.32224-1-aring@mojatatu.com> (raw)
This patch fixes the following sparse warning about mismatch rcu
attribute for address space annotation:
...
error: incompatible types in comparison expression (different modifiers)
error: incompatible types in comparison expression (different address spaces)
...
Some __rcu annotation was at non-pointers list head structures and one was
missing in edge information which is used by rcu_assign_pointer() to
update edge setting information.

Fixes: f25da51fdc38 ("ieee802154: hwsim: add replacement for fakelb")
