Subject: [PATCH] iw_cxgb4: Use proper enumerated type in c4iw_bar2_addrs
Date: Mon, 24 Sep 2018 12:29:03 -0700 [thread overview]
Message-ID: <20180924192903.16796-1-natechancellor@gmail.com> (raw)
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
