Subject: [PATCH v2 11/11] net: dsa: hellcreek: Get rid of custom led_init_default_state_get()
Date: Fri,  5 Aug 2022 18:49:07 +0300	[thread overview]
Message-ID: <20220805154907.32263-12-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220805154907.32263-1-andriy.shevchenko@linux.intel.com>

LED core provides a helper to parse default state from firmware node.
Use it instead of custom implementation.
