[PATCH net-next 04/11] batman-adv: use GFP_KERNEL allocations for the wifi detection cache

From: Sven Eckelmann <[email protected]>

The batadv_wifi_net_device_insert() is called with ASSERT_RTNL() held, but
not inside a spinlock or another context which prevents "might_sleep"
functions. To relax the requirements for the allocator, use GFP_KERNEL.
