From d3a315795b4ce8b105a64a90699103121bde04a8 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 24 Sep 2018 14:34:53 -0700 Subject: [PATCH] qed: Avoid implicit enum conversion in qed_roce_mode_to_flavor 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.
