Subject: [PATCH] i40iw: Fix error handling in i40iw_manage_arp_cache()
Date: Wed, 22 Apr 2020 12:22:11 +0300	[thread overview]
Message-ID: <20200422092211.GA195357@mwanda> (raw)

The i40iw_arp_table() function can return -EOVERFLOW if
i40iw_alloc_resource() fails so we can't just test for "== -1".

Fixes: 4e9042e647ff ("i40iw: add hw and utils files")
