m68k/math-emu: unsigned issue, 'unsigned long' will never be less than zero
'oldmant.m32[1]' is 'unsigned long' which can never be '< 0', and the original author wanted to check whether the highest bit is set. So make the bit test explicit (which is better than casting from 'unsigned long' to 'long'). The related warning: (with EXTRA_CFLAGS=-W ARCH=m68k for allmodconfig) arch/m68k/math-emu/fp_arith.c:522:4: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] Signed-off-by: Chen Gang <gang.chen@asianux.com> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
