[PATCH] ath: switch from 'pci_' to 'dma_' API
From: Christophe JAILLET <hidden>
Date: 2021-06-26 15:30:15
Also in:
ath11k, kernel-janitors, lkml, netdev
Subsystem:
atheros ath generic utilities, atheros ath5k wireless driver, qualcomm atheros ath10k wireless driver, qualcomm atheros ath11k wireless driver, qualcomm atheros ath9k wireless driver, the rest · Maintainers:
Jeff Johnson, Jiri Slaby, Nick Kossifidis, Luis Chamberlain, Toke Høiland-Jørgensen, Linus Torvalds
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()'.
