From 36b7dd48b3aaacc28dded0e88a2a4d02e09be870 Mon Sep 17 00:00:00 2001 From: Martin Kaiser Date: Mon, 23 Jan 2023 21:53:24 +0100 Subject: [PATCH] staging: r8188eu: simplify the sta loop in rtw_dequeue_xframe Use list_for_each_entry_safe to iterate over the station entries in function rtw_dequeue_xframe instead of coding the loop manually. We have to use the safe version, the loop body may remove a station from the list over which we iterate.
