From 2d946e5bcdabc1deef72d01bc92a2801c71d6d8d Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 9 Sep 2018 21:26:23 +0200 Subject: MIPS: lantiq: dma: add dev pointer dma_zalloc_coherent() now crashes if no dev pointer is given. Add a dev pointer to the ltq_dma_channel structure and fill it in the driver using it. This fixes a bug introduced in kernel 4.19. Signed-off-by: Hauke Mehrtens Signed-off-by: David S.
