Description

dragonfly/sys/dev/drm/radeon/radeon_uvd.c:897] -> [dragonfly/sys/dev/drm/radeon/radeon_uvd.c:903]: (warning) Identical condition 'vclk_div>pd_max', second condition is always false

Source code is

if (vclk_div > pd_max)
            break; /* vco is too big, it has to stop */
/* calc dclk divider with current vco freq /
        dclk_div = radeon_uvd_calc_upll_post_div(vco_freq, dclk,
                             pd_min, pd_even);
        if (vclk_div > pd_max)
            break; / vco is too big, it has to stop */

Maybe the 2nd if would be better if it sanity checked dclk_div, like

if (dclk_div > pd_max)
            break; /* vco is too big, it has to stop */
