Subject: [PATCH v2 6/9] pwm: lpss: Use DEFINE_RUNTIME_DEV_PM_OPS() and pm_ptr() macros
Date:   Thu,  8 Sep 2022 16:56:55 +0300
Message-Id: <20220908135658.64463-7-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20220908135658.64463-1-andriy.shevchenko@linux.intel.com>
References: <20220908135658.64463-1-andriy.shevchenko@linux.intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Using these new macros allows the compiler to remove the unused dev_pm_ops
structure and related functions if !CONFIG_PM without the need to mark
the functions __maybe_unused.
