From: Andre Guedes Date: Wed, 18 Mar 2020 23:00:53 +0000 (-0700) Subject: igc: Change igc_add_mac_filter() returning value X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=58184b8ff0786b219772016a50ce07c6b3020846;p=openwrt%2Fstaging%2Fblogic.git igc: Change igc_add_mac_filter() returning value In case of success, igc_add_mac_filter() returns the index in adapter->mac_table where the requested filter was added. This information, however, is not used by any caller of that function. In fact, callers have extra code just to handle this returning index as 0 (success). So this patch changes the function to return 0 on success instead, and cleans up the extra code.
