Subject: [PATCH v6 09/12] watchdog: simatic-ipc-wdt: convert to use P2SB accessor
Date: Mon, 6 Jun 2022 19:41:35 +0300 [thread overview]
Message-ID: <20220606164138.66535-10-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220606164138.66535-1-andriy.shevchenko@linux.intel.com>
From: Henning Schild <henning.schild@siemens.com>
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.
