microblaze: fix iounmap prototype
The missing 'volatile' keyword on the iounmap argument leads to lots of harmless warnings in an allmodconfig build: sound/pci/echoaudio/echoaudio.c:1879:10: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
