Hello there,
I just tried out static analyser cppcheck on linux-6.5. It said:
linux-6.5/drivers/thunderbolt/tmu.c:385:50: style: Expression is always false because 'else if' condition matches previous condition at line 383. [multiCondition]
Source code is
if (tmu_rates[TB_SWITCH_TMU_MODE_LOWRES] == rate)
sw->tmu.mode = TB_SWITCH_TMU_MODE_LOWRES;
else if (tmu_rates[TB_SWITCH_TMU_MODE_LOWRES] == rate)
sw->tmu.mode = TB_SWITCH_TMU_MODE_HIFI_UNI;
Regards
David Binderman

Thanks for the report. Indeed, this should be
else if (tmu_rates[TB_SWITCH_TMU_MODE_HIFI_UNI] == rate)
sw->tmu.mode = TB_SWITCH_TMU_MODE_HIFI_UNI;
I will fix it up and send out after v6.6-rc1 is released.
