Subject[PATCH] net: core: devlink.c: Use built-in RCU list checking
Date
From: Madhuparna Bhowmik <madhuparnabhowmik10@gmail.com>

list_for_each_entry_rcu() has built-in RCU and lock checking.

Pass cond argument to list_for_each_entry_rcu() to silence
false lockdep warning when CONFIG_PROVE_RCU_LIST is enabled
by default.
