From 2ae155e7eeb8367990fdffda5c5c5b5ccc99aeb7 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 10 Mar 2020 20:36:16 -0700 Subject: [PATCH] net: fec: validate the new settings in fec_enet_set_coalesce() fec_enet_set_coalesce() validates the previously set params and if they are within range proceeds to apply the new ones. The new ones, however, are not validated. This seems backwards, probably a copy-paste error? Compile tested only.
