+Subject: i3c: master: svc: Fix implicit fallthrough in svc_i3c_master_ibi_work()
+
+From: Nathan Chancellor <nathan@kernel.org>
+
+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.
