Subject: [PATCH v3 03/17] i3c: renesas: Follow the reset deassert order used in probe
Date: Mon,  8 Jun 2026 23:15:29 +0300	[thread overview]
Message-ID: <20260608201543.804902-4-claudiu.beznea@kernel.org> (raw)
In-Reply-To: <20260608201543.804902-1-claudiu.beznea@kernel.org>

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Use the same reset deassert order in the resume and probe paths to avoid
potential failures due to ordering differences.

Fixes: e7218986319b ("i3c: renesas: Add suspend/resume support")
