4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko andriy.shevchenko@linux.intel.com
commit efc4a13724b852ddaa3358402a8dec024ffbcb17 upstream.
Currently the 32-bit device address only is supported for DMA. However, starting from Intel Sunrisepoint PCH the DMA address of the device FIFO can be 64-bit.
Change the respective variable to be compatible with DMA engine expectations, i.e. to phys_addr_t.
