[PATCH] hwmon: (oxp-sensors) Add missing breaks to fix -Wimplicit-fallthrough with clang

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



clang warns (or errors due to CONFIG_WERROR):

  drivers/hwmon/oxp-sensors.c:481:3: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
  drivers/hwmon/oxp-sensors.c:553:3: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
  drivers/hwmon/oxp-sensors.c:556:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
  drivers/hwmon/oxp-sensors.c:607:3: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

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 breaks to
silence the warnings.
