The flat_get_addr_from_rp() macro does not use the 'persistent' argument on ARM, causing a harmless compiler warning. A cast to void removes that warning. Without this patch, building at91x40_defconfig results in: fs/binfmt_flat.c: In function 'load_flat_file': fs/binfmt_flat.c:746:17: warning: unused variable 'persistent' [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Greg Ungerer <redacted> Cc: Russell King <redacted> Cc: Bryan Wu <redacted>
Acked-by: Greg Ungerer <redacted> I can pick this one up to, and push to the arm-soc tree. Regards Greg
