nds32: Mark expected switch fall-throughs
Mark switch cases where we are expecting to fall through. This patch fixes the following warnings (Building: allmodconfig nds32): include/math-emu/soft-fp.h:124:8: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/nds32/kernel/signal.c:362:20: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/nds32/kernel/signal.c:315:7: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:417:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:430:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:310:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:320:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:310:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:320:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/soft-fp.h:124:8: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:417:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:430:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:310:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:320:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:310:11: warning: this statement may fall through [-Wimplicit-fallthrough=] include/math-emu/op-common.h:320:11: warning: this statement may fall through [-Wimplicit-fallthrough=] Reported-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Gustavo A.
