Message-ID: <20210925124637.303-1-caihuoqing@baidu.com>
Date: Sat, 25 Sep 2021 20:46:36 +0800
From: Cai Huoqing <caihuoqing@...du.com>

CC: "James E.J. Bottomley" <James.Bottomley@...senPartnership.com>,

<linux-kernel@...r.kernel.org>
Subject: [PATCH] parisc: Fix function names in print messages and coments
Use dma_xxx_xxx() instead of pci_xxx_xxx(),
because the pci function wrappers are not called here.
