Subject: [PATCH 03/17] i3c: master: Update hot-join flag only on success
Date: Fri, 19 Dec 2025 16:45:20 +0200 [thread overview]
Message-ID: <20251219144534.84391-4-adrian.hunter@intel.com> (raw)
In-Reply-To: <20251219144534.84391-1-adrian.hunter@intel.com>
To prevent inconsistent state when an error occurs, ensure the hot-join
flag is updated only when enabling or disabling hot-join succeeds.
