Message-Id: <20221126141806.62205-1-andriy.shevchenko@linux.intel.com> Date: Sat, 26 Nov 2022 16:18:02 +0200 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: Rasmus Villemoes <linux@...musvillemoes.dk>, linux-rtc@...r.kernel.org, linux-kernel@...r.kernel.org, linux-hwmon@...r.kernel.org Cc: Alessandro Zummo <a.zummo@...ertech.it>, Alexandre Belloni <alexandre.belloni@...tlin.com>, Jean Delvare <jdelvare@...e.com>, Guenter Roeck <linux@...ck-us.net>, Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH v1 1/5] rtc: isl12022: Get rid of unneeded private struct isl12022 First of all, the struct rtc_device pointer is kept in the managed resources, no need to keep it outside (no users in the driver). Second, replace private struct isl12022 with a regmap.
