Subject: [PATCH 5.10 21/83] bus: ti-sysc: Add break in switch statement in sysc_init_soc()

From: Nathan Chancellor <nathan@...nel.org>

[ Upstream commit e879f855e590b40fe3c79f2fbd8f65ca3c724120 ]

After commit a6d90e9f2232 ("bus: ti-sysc: AM3: RNG is GP only"), clang
with -Wimplicit-fallthrough enabled warns:

drivers/bus/ti-sysc.c:2958:3: warning: unannotated fall-through between
switch labels [-Wimplicit-fallthrough]
                default:
                ^
drivers/bus/ti-sysc.c:2958:3: note: insert 'break;' to avoid
fall-through
                default:
                ^
                break;
1 warning generated.

Clang's version of this warning is a little bit more pedantic than
GCC's. Add the missing break to satisfy it to match what has been done
all over the kernel tree.
