ARM: 8584/1: floppy: avoid gcc-6 warning
commit dd665be0e243873343a28e18f9f345927b658daf 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.
