Subject: [PATCH 1/3] drm/gma500/oaktrail_hdmi: fix i2c adapter leak on setup
Date: Fri, 8 May 2026 16:44:44 +0200 [thread overview]
Message-ID: <20260508144446.59722-2-johan@kernel.org> (raw)
In-Reply-To: <20260508144446.59722-1-johan@kernel.org>
Make sure to drop the reference taken to the I2C adapter (and its
module) when setting up HDMI to allow the adapter to be deregistered.
Fixes: 1b082ccf5901 ("gma500: Add Oaktrail support")
