commit e8d2d287e26d9bd9114cf258a123a6b70812442e upstream.
Clang warns (or errors with CONFIG_WERROR=y):
drivers/i3c/master/svc-i3c-master.c:596:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough] 596 | default: | ^ drivers/i3c/master/svc-i3c-master.c:596:2: note: insert 'break;' to avoid fall-through 596 | 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.
