hwmon: (smpro-hwmon) Improve switch statments in smpro_is_visible()
Clang warns:
drivers/hwmon/smpro-hwmon.c:378:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
default:
^
drivers/hwmon/smpro-hwmon.c:378:2: note: insert 'break;' to avoid fall-through
default:
^
break;
1 error generated.
Clang is a little more pedantic than GCC, which does not warn when
falling 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, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return.
Add the missing break to silence the warning. Additionally, adjust the
indentation of a break and add a default case to the inner switch
statement.
