mdadm: Add Wimplicit-fallthrough=0 in Makefile
There are many errors like 'error: this statement may fall through'. But the logic is right. So add the flag Wimplicit-fallthrough=0 to disable the error messages. The method I use is from https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html #index-Wimplicit-fallthrough-375 Signed-off-by: Xiao Ni <xni@redhat.com> Signed-off-by: Jes Sorensen <Jes.Sorensen@gmail.com>
