bcm63xx: prevent fall-through in kernel patches for 5.4
In kernel 5.4 -Werror=implicit-fallthrough is treated as error: arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock': arch/mips/bcm63xx/cpu.c:158:2: error: this statement may fall through [-Werror=implicit-fallthrough=] { ^ arch/mips/bcm63xx/cpu.c:179:2: note: here case BCM6328_CPU_ID: ^~~~ cc1: all warnings being treated as errors This can be fixed by adding "Fall through" as a comment where intended, and has to be fixed by returning a proper default otherwise. In case of the default clock frequency for BCM6318 we fixed this by returning the default value taken from BCM6328 and BCM6362. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
