From 99a1230d9d1cb5d52bb37b8c03f3931502f0e44d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 23 May 2014 16:13:57 +0200 Subject: [PATCH] iwlwifi: mvm: validate that we don't send zero quota The firmware currently deals with zero quota for a given binding, but it seems odd to send that down. Make sure that we don't do that.
