From c17ffe008463d3a07b633dd0e956f7c1a3a7c347 Mon Sep 17 00:00:00 2001 From: Martin Kaiser Date: Sat, 11 Feb 2023 18:02:23 +0100 Subject: staging: r8188eu: replace hand coded loop with list_for_each_entry In function rtw_get_stainfo, we can use list_for_each_entry to iterate over the list of stations and make the code a bit simpler.
