Date: Thu, 3 Dec 2020 09:01:30 +0800 From: Youling Tang <tangyouling@...ngson.cn> To: Neil Horman <nhorman@...driver.com>, Seth Heasley <seth.heasley@...el.com> Cc: Wolfram Sang <wsa@...nel.org>, linux-i2c@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2] i2c: ismt: Use dma_set_mask_and_coherent 'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose.
