From 759273c3c429ffbd8f24655fd0480cd408a1804c Mon Sep 17 00:00:00 2001 From: Henning Schild Date: Mon, 6 Jun 2022 19:41:36 +0300 Subject: leds: simatic-ipc-leds: Convert to use P2SB accessor Since we have a common P2SB accessor in tree we may use it instead of open coded variants. Replace custom code by p2sb_bar() call.
