staging: slicoss: Remove dma_addr_t cast compilation warnings
Eliminate some warnings by casting to unsigned long before casting a dma_addr_t value to a pointer. btw: Does slicoss always work on x86-32? Is a pshmem guaranteed to be accessible by a 32 bit address? Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
