From: Luca Coelho luciano.coelho@intel.com Date: Thu, 29 Aug 2019 11:13:46 +0300 Subject: [PATCH] iwlwifi: assign directly to iwl_trans->cfg in QuZ detection

We were erroneously assigning the new configuration to a local variable cfg, but that was not being assigned to anything, so the change was getting lost. Assign directly to iwl_trans->cfg instead.
