Subject: [PATCH] net: neterion: vxge: Remove unnecessary parentheses
Date: Thu, 20 Sep 2018 13:37:33 -0700 [thread overview]
Message-ID: <20180920203733.32019-1-natechancellor@gmail.com> (raw)
Clang warns when multiple pairs of parentheses are used for a single
conditional statement.
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:2265:31: warning:
equality comparison with extraneous parentheses [-Wparentheses-equality]
if ((hldev->config.intr_mode ==
VXGE_HW_INTR_MODE_MSIX_ONE_SHOT))
~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:2265:31: note: remove
extraneous parentheses around the comparison to silence this warning
if ((hldev->config.intr_mode ==
VXGE_HW_INTR_MODE_MSIX_ONE_SHOT))
~ ^ ~
drivers/net/ethernet/neterion/vxge/vxge-traffic.c:2265:31: note: use '='
to turn this equality comparison into an assignment
if ((hldev->config.intr_mode ==
VXGE_HW_INTR_MODE_MSIX_ONE_SHOT))
^~
