Subject: [PATCH v1 1/1] leds: sun50i-a100: Convert to be agnostic to property provider
Date: Thu, 14 Dec 2023 21:21:31 +0200
Message-ID: <20231214192131.1309912-1-andriy.shevchenko@linux.intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Convert the driver to be agnostic to the property provider.
LEDS subsytem is not dependent on OF, so no need to make drivers
be a such.
