[ Upstream commit d3a315795b4ce8b105a64a90699103121bde04a8 ]
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.
