From 36d7859a3ffc2bc1eb15297cdb465a5b4aa65e7f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 24 Apr 2025 15:38:26 +0300 Subject: [PATCH] wifi: iwlwifi: mld: rx: simplify channel handling There's no need to have the channel in phy_data, this code only supports one descriptor format so can use it directly from there.
