drivers: uio_dmem_genirq: Don't mix address spaces for dynamic region vaddr
Assigning the virtual address returned from dma_alloc_coherent to the the
internal_addr element of uioinfo produces the following sparse errors since
internal_addr is a void __iomem * and dma_alloc_coherent returns void *.
+ drivers/uio/uio_dmem_genirq.c:65:39: sparse: incorrect type in assignment (different address spaces)
drivers/uio/uio_dmem_genirq.c:65:39: expected void [noderef] <asn:2>*internal_addr
drivers/uio/uio_dmem_genirq.c:65:39: got void *[assigned] addr
+ drivers/uio/uio_dmem_genirq.c:93:17: sparse: incorrect type in argument 3 (different address spaces)
drivers/uio/uio_dmem_genirq.c:93:17: expected void *vaddr
drivers/uio/uio_dmem_genirq.c:93:17: got void [noderef] <asn:2>*internal_addr
Store the void * in the driver's private data instead.
