Subject: [PATCH 05/15] reset: warn on reset-gpio release
Date: Mon, 05 Jan 2026 15:15:24 +0100 [thread overview]
Message-ID: <20260105-reset-core-refactor-v1-5-ac443103498d@oss.qualcomm.com> (raw)
In-Reply-To: <20260105-reset-core-refactor-v1-0-ac443103498d@oss.qualcomm.com>
While we implement an empty .release() callback for reset-gpio (driver
core requires it), this function will never actually be called as nobody
ever removes the device and the last reference is not dropped anywhere.
This is by design - once created, the reset-gpio device stays in memory.
Make the .release() callback emit a warning, should it ever be called
due to a programming bug.
