[PATCH] sound: ppc: beep: fix clang -Wimplicit-fallthrough
Clang warns:
sound/ppc/beep.c:103:2: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough] case SND_TONE: break; ^ sound/ppc/beep.c:103:2: note: insert 'break;' to avoid fall-through case SND_TONE: break; ^ break; 1 warning generated.
Clang is more pedantic than GCC, which does not warn when failing through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst. Add athe missing break to silence the warning.
