cppcheck rightfully complains about:
drivers/i2c/busses/i2c-brcmstb.c:319:7: warning: Condition 'CMD_RD' is always true [knownConditionTrueFalse]
drivers/i2c/busses/i2c-brcmstb.c:319:17: warning: Condition 'CMD_WR' is always false [knownConditionTrueFalse]
if ((CMD_RD || CMD_WR) &&
Compare the values to the 'cmd' variable.
Fixes: dd1aa2524bc5 ("i2c: brcmstb: Add Broadcom settop SoC i2c controller driver")
