Clang warns:
drivers/net/ethernet/intel/ice/ice_lib.c:1906:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough] default: ^ drivers/net/ethernet/intel/ice/ice_lib.c:1906:2: 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.
