Subject: [PATCH v2 2/2] drm/panthor: skip regulator setup if no such prop
Date: Sun, 28 Sep 2025 17:03:34 +0800	[thread overview]
Message-ID: <20250928090334.35389-2-jiyu.yang@oss.nxp.com> (raw)
In-Reply-To: <20250928090334.35389-1-jiyu.yang@oss.nxp.com>

From: Rain Yang <jiyu.yang@nxp.com>

The regulator is optional, skip the setup instead of returning an
error if it is not present
