dmam_alloc_coherent does not return a __iomem pointer. here is its prototype: void * dmam_alloc_coherent(struct device *dev, size_t size, dma_addr_t *dma_handle, gfp_t gfp) This fixes these sparse warnings: drivers/staging/goldfish/goldfish_audio.c:134:43: warning: incorrect type in argument 2 (different address spaces) drivers/staging/goldfish/goldfish_audio.c:134:43: expected void const *from drivers/staging/goldfish/goldfish_audio.c:134:43: got char [noderef] <asn:2>*read_buffer drivers/staging/goldfish/goldfish_audio.c:167:36: warning: incorrect type in argument 1 (different address spaces) drivers/staging/goldfish/goldfish_audio.c:167:36: expected void *to drivers/staging/goldfish/goldfish_audio.c:167:36: got char [noderef] <asn:2>*[assigned] kbuf drivers/staging/goldfish/goldfish_audio.c:296:27: warning: incorrect type in assignment (different address spaces) drivers/staging/goldfish/goldfish_audio.c:296:27: expected char [noderef] <asn:2>*buffer_virt drivers/staging/goldfish/goldfish_audio.c:296:27: got void * Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Acked-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Audio ----- - Move to using the ALSA framework not faking it - Fix the wrong user page DMA (moving to ALSA may fix that too) NAND ---- - Remove excess checking of parameters in calls - Use dma coherent memory not kmalloc/__pa for the memory (this is just a cleanliness issue not a correctness one)
