Clang warns when one enumerated type is implicitly converted to another.
drivers/net/ethernet/qlogic/qed/qed_roce.c:153:12: warning: implicit
conversion from enumeration type 'enum roce_mode' to different
enumeration type 'enum roce_flavor' [-Wenum-conversion]
flavor = ROCE_V2_IPV6;
~ ^~~~~~~~~~~~
drivers/net/ethernet/qlogic/qed/qed_roce.c:156:12: warning: implicit
conversion from enumeration type 'enum roce_mode' to different
enumeration type 'enum roce_flavor' [-Wenum-conversion]
flavor = MAX_ROCE_MODE;
~ ^~~~~~~~~~~~~
2 warnings generated.
Use the appropriate values from the expected type, roce_flavor:
ROCE_V2_IPV6 = RROCE_IPV6 = 2
MAX_ROCE_MODE = MAX_ROCE_FLAVOR = 3
While we're add it, ditch the local variable flavor, we can just return
the value directly from the switch statement.
