From 8c91562075e8621f6d9a11cfcf31a71a7203cbbe Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Wed, 15 Jun 2016 17:49:05 +0100 Subject: [PATCH] sfc: Refactor checks for invalid filter ID Nearly every time we call efx_ef10_filter_remove_unsafe, we first check for EFX_EF10_FILTER_ID_INVALID, in which case we do nothing. So move that check into the function, simplifying all the call sites. Also, change the return type to void, since none of the callers check it. Signed-off-by: Edward Cree Signed-off-by: David S.
