Subject: [PATCH -next 12/21] spi: cadence: switch to use modern name
Date: Fri, 28 Jul 2023 17:32:12 +0800	[thread overview]
Message-ID: <20230728093221.3312026-13-yangyingliang@huawei.com> (raw)
In-Reply-To: <20230728093221.3312026-1-yangyingliang@huawei.com>

Change legacy name master/slave to modern name host/target or controller.

No functional changed.
