From 91f02b3dd8311b48c021e8667a84dfc2d6445a03 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Mon, 10 Aug 2015 21:15:55 +0200 Subject: [PATCH] mac802154: cfg: remove test and set checks This patch removes several checks if a value is really changed. This makes only sense if we have another layer call e.g. calling the driver_ops which is done by callbacks like "set_channel". For MAC settings which need to be set by phy registers (if the phy supports that handling) this is set by doing an interface up currently and are not direct driver_ops calls, so we remove the checks from these configuration callbacks.
