linux-4.6-rc2/drivers/gpu/drm/radeon/si_dpm.c: multiple problems ?

[David Binderman]

Hello there,

1.

linux-4.6-rc2/drivers/gpu/drm/radeon/si_dpm.c:3788]: (style) Condition 'td==0' 
is always true

Source code is

    enum r600_td td = R600_TD_DFLT;

    for (i = 0; i < R600_PM_NUMBER_OF_TC; i++)
        WREG32(CG_FFCT_0 + (i * 4), (UTC_0(r600_utc[i]) | 
DTC_0(r600_dtc[i])));

    if (td == R600_TD_AUTO)
