Subject: [PATCH 1/2] net: pch_gbe: Use dma_set_mask_and_coherent to simplify code
Date: Sat, 21 Nov 2020 10:03:02 +0100	[thread overview]
Message-ID: <20201121090302.1332491-1-christophe.jaillet@wanadoo.fr> (raw)

'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.
