Subject: [PATCH v4 10/13] drm/bridge: tc358762: Move tc358762_init() into tc358762_enable()
Date: Mon, 07 Sep 2026 14:28:05 +0300 [thread overview]
Message-ID: <20260907-tc358762-fixes-v4-10-e3fc3ab5cd83@ideasonboard.com> (raw)
In-Reply-To: <20260907-tc358762-fixes-v4-0-e3fc3ab5cd83@ideasonboard.com>
The only thing tc358762_enable() does is call tc358762_init(). Inline
the tc358762_init() into tc358762_enable(), for simplicity and to make
it easier to improve the tc358762_enable() in the following commits. No
functional change.
