Subject: [PATCH] ath: switch from 'pci_' to 'dma_' API
Date: Sat, 26 Jun 2021 17:25:04 +0200	[thread overview]
Message-ID: <9150bd6cde9ad592aff8ee3ad94dffa90b004e89.1624720959.git.christophe.jaillet@wanadoo.fr> (raw)

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

While at it, some 'dma_set_mask()/dma_set_coherent_mask()' have been
updated to a much less verbose 'dma_set_mask_and_coherent()'.
