Pass the easily -available struct device from the platform_device to remedy this. - -Also use GFP_KERNEL instead of GFP_ATOMIC as the gfp_t for the memory -allocation, as we aren't in interrupt context or under a lock. - -Note that this whole function looks somewhat bogus given that we never -even look at the returned dma address, and the CPHYSADDR magic on -a returned noncached mapping looks "interesting". But I'll leave -that to people more familiar with the code to sort out. - -Signed-off-by: Christoph Hellwig <hch@lst.de> -Signed-off-by: Paul Burton <paul.burton@mips.com> -Cc: John Crispin <john@phrozen.org> -Cc: Vinod Koul <vkoul@kernel.org> -Cc: Dmitry Tarnyagin <dmitry.tarnyagin@lockless.no> -Cc: Nicolas Ferre <nicolas.ferre@microchip.com> -Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> -Cc: Felipe Balbi <balbi@kernel.org> -Cc: linux-mips@vger.kernel.org -Cc: linux-kernel@vger.kernel.org -Cc: dmaengine@vger.kernel.org -Cc: netdev@vger.kernel.org -Cc: linux-usb@vger.kernel.org -Cc: linux-fbdev@vger.kernel.org -Cc: alsa-devel@alsa-project.org -Cc: iommu@lists.linux-foundation.org ---- - arch/mips/lantiq/xway/vmmc.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - ---- a/arch/mips/lantiq/xway/vmmc.c -+++ b/arch/mips/lantiq/xway/vmmc.c -@@ -31,8 +31,8 @@ static int vmmc_probe(struct platform_de - dma_addr_t dma; - - cp1_base = -- (void *) CPHYSADDR(dma_alloc_coherent(NULL, CP1_SIZE, -- &dma, GFP_ATOMIC)); -+ (void *) CPHYSADDR(dma_alloc_coherent(&pdev->dev, CP1_SIZE, -+ &dma, GFP_KERNEL)); - - gpio_count = of_gpio_count(pdev->dev.of_node); - while (gpio_count > 0) { |
