Subject: [PATCH 6/6] usb: typec: Use FIELD_MODIFY()
Date: Fri,  1 May 2026 00:39:19 +0800	[thread overview]
Message-ID: <20260430163919.47372-7-18255117159@163.com> (raw)
In-Reply-To: <20260430163919.47372-1-18255117159@163.com>

Use FIELD_MODIFY() to remove open-coded bit manipulation.
No functional change intended.
