commit dd665be0 upstream. gcc-6.0 warns about comparisons between two identical expressions, which is what we get in the floppy driver when writing to the FD_DOR register: drivers/block/floppy.c: In function 'set_dor': drivers/block/floppy.c:810:44: error: self-comparison always evaluates to true [-Werror=tautological-compare] fd_outb(newdor, FD_DOR); It would be nice to use a static inline function instead of the macro, to avoid the warning, but we cannot do that because the FD_DOR definition is incomplete at this point. Adding a cast to (u32) is a harmless way to shut up the warning, just not very nice. Signed-off-by:
