[ Upstream commit 1b571086e869395b6a11ab24186b0104fe05c057 ]
Clang warns when one enumerated type is implicitly converted to another.
drivers/infiniband/hw/cxgb4/qp.c:287:8: warning: implicit conversion from enumeration type 'enum t4_bar2_qtype' to different enumeration type 'enum cxgb4_bar2_qtype' [-Wenum-conversion] T4_BAR2_QTYPE_EGRESS, ^~~~~~~~~~~~~~~~~~~~
c4iw_bar2_addrs expects a value from enum cxgb4_bar2_qtype so use the corresponding values from that type so Clang is satisfied without changing the meaning of the code.
T4_BAR2_QTYPE_EGRESS = CXGB4_BAR2_QTYPE_EGRESS = 0 T4_BAR2_QTYPE_INGRESS = CXGB4_BAR2_QTYPE_INGRESS = 1
