Subject: [PATCH v2 21/21] PM: Switch to use %ptR
Date:   Tue, 20 Feb 2018 23:44:00 +0200
Message-Id: <20180220214400.66749-22-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20180220214400.66749-1-andriy.shevchenko@linux.intel.com>
References: <20180220214400.66749-1-andriy.shevchenko@linux.intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use %ptR instead of open coded variant to print content of
struct rtc_time in human readable format.
