From 05d5752027d02ca9204d1ece5074d41000fee23d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 31 Mar 2010 08:59:17 -0700 Subject: [PATCH] iwlwifi: clean up last_phy_res The last_phy_res[100] variable is used in an odd way. The first byte of it is used as a flag, and the rest as the data. Thus, the array need only be 61 bytes, since it is just the flag and a struct iwl_rx_phy_res (which is 60 bytes). Clean this up by splitting the variable into two: last_phy_res and last_phy_res_valid, using correct types for both (struct and bool). While doing all this also move the variables to the _agn part of the hw-specific union since they only apply to A-MPDUs.
