Subject: [PATCH v3 09/17] i3c: renesas: Use reset_control_bulk_{assert, deassert}()
Date: Mon, 8 Jun 2026 23:15:35 +0300 [thread overview]
Message-ID: <20260608201543.804902-10-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 reset_control_bulk_assert() and reset_control_bulk_deassert() in the
suspend and resume paths to simplify the code.
