Date: Mon, 24 Aug 2020 16:18:51 +0100 From: Edward Cree <ecree@...arflare.com> To: <linux-net-drivers@...arflare.com>, <davem@...emloft.net> CC: <netdev@...r.kernel.org> Subject: [PATCH net] sfc: fix boolreturn.cocci warning and rename function check_fcs() was returning bool as 0/1, which was a sign that the sense of the function was unclear: false was good, which doesn't really match a name like 'check_$thing'. So rename it to ef100_has_fcs_error(), and use proper booleans in the return statements.
