Subject: [PATCH] rsxx: switch from 'pci_free_consistent()' to 'dma_free_coherent()'
Date: Sat, 11 Jul 2020 08:46:47 +0200 [thread overview]
Message-ID: <20200711064647.247564-1-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 bellow.
It has been compile tested.
This also aligns code with what is in use in '/rsxx/dma.c'
