Subject: [PATCH V2 03/20] i3c: master: Update hot-join flag only on success
Date: Thu,  8 Jan 2026 10:05:41 +0200	[thread overview]
Message-ID: <20260108080558.21767-4-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260108080558.21767-1-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.

Fixes: 317bacf960a48 ("i3c: master: add enable(disable) hot join in sys entry")
