Subject: [PATCH v1 06/28] leds: el15203000: Introduce to_el15203000_led() helper
Date: Mon, 10 May 2021 12:50:23 +0300 [thread overview]
Message-ID: <20210510095045.3299382-7-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20210510095045.3299382-1-andy.shevchenko@gmail.com>
Introduce a helper to replace open coded container_of() calls.
At the same time move ldev member to be first in the struct el15203000_led,
that makes container_of() effectivelly a no-op.
