Hi list,
Smatch complains about this:
drivers/gpu/drm/radeon/radeon_display.c +563 radeon_compute_pll_legacy(115)
warn: unsigned 'error' is never less than zero.
561 if (pll->flags & RADEON_PLL_PREFER_CLOSEST_LOWER) {
562 error = freq - current_freq;
563 error = error < 0 ? 0xffffffff : error;
^^^^^^^^^
"error" is unsigned so it's never less than zero here.
564 } else
565 error = abs(current_freq - freq);
regards,
dan carpenter
