CVE-2023-54025

Description

In the Linux kernel, the following vulnerability has been resolved:wifi: rsi: Do not configure WoWlan in shutdown hook if not enabledIn case WoWlan was never configured during the operation of the system,the hw->wiphy->wowlan_config will be null. rsi_config_wowlan() checkswhether wowlan_config is non-null and if it is not, then WARNs about it.The warning is valid, as during normal operation the rsi_config_wowlan()should only ever be called with non-null wowlan_config. In shutdown thisrsi_config_wowlan() should only ever be called if WoWlan was configuredbefore by the user.Add checks for non-null wowlan_config into the shutdown hook. While at it,check whether the wiphy is also non-null before accessing wowlan_config .Drop the single-use wowlan_config variable, just inline it into functioncall.
