Subject: [PATCH 4/8] i2c: core: disable runtime PM on adapter registration failure
Date: Tue, 5 May 2026 16:25:43 +0200 [thread overview]
Message-ID: <20260505142547.795054-5-johan@kernel.org> (raw)
In-Reply-To: <20260505142547.795054-1-johan@kernel.org>
Runtime PM is disabled by driver core when deregistering a device (and
on registration failure) but add an explicit disable to balance the
enable call when adapter registration fails for symmetry.
Fixes: 23a698fe65ec ("i2c: core: treat EPROBE_DEFER when acquiring SCL/SDA GPIOs")
