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> --- arch/microblaze/include/asm/io.h | 2 +- arch/microblaze/mm/pgtable.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) -- 2.9.0
