Subject: [PATCH v2 3/7] pwm: core: Convert to use fwnode for matching
Date: Mon, 31 May 2021 22:49:43 +0300 [thread overview]
Message-ID: <20210531194947.10770-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210531194947.10770-1-andriy.shevchenko@linux.intel.com>
When we traverse the list of the registered PWM controllers,
use fwnode to match. This will help for further cleanup.
