------------------ From: Arnd Bergmann <[email protected]> commit fb6fafbc7de4a813bb5364358bbe27f71e62b24a upstream. clang points out a harmless signed integer overflow: drivers/net/ethernet/3com/3c515.c:1530:66: error: implicit conversion from 'int' to 'short' changes value from 32783 to -32753 [-Werror,-Wconstant-conversion] new_mode = SetRxFilter | RxStation | RxMulticast | RxBroadcast | RxProm; ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~ drivers/net/ethernet/3com/3c515.c:1532:52: error: implicit conversion from 'int' to 'short' changes value from 32775 to -32761 [-Werror,-Wconstant-conversion] new_mode = SetRxFilter | RxStation | RxMulticast | RxBroadcast; ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~ drivers/net/ethernet/3com/3c515.c:1534:38: error: implicit conversion from 'int' to 'short' changes value from 32773 to -32763 [-Werror,-Wconstant-conversion] new_mode = SetRxFilter | RxStation | RxBroadcast; ~ ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~ Make the variable unsigned to avoid the overflow.
