conditional statements.

drivers/infiniband/hw/nes/nes_hw.c:1446:27: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        } while ((temp_phy_data2 == temp_phy_data));
                  ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
drivers/infiniband/hw/nes/nes_hw.c:1446:27: note: remove extraneous
parentheses around the comparison to silence this warning
        } while ((temp_phy_data2 == temp_phy_data));
                 ~               ^               ~
drivers/infiniband/hw/nes/nes_hw.c:1446:27: note: use '=' to turn this
equality comparison into an assignment
        } while ((temp_phy_data2 == temp_phy_data));
                                 ^~
                                 =
