[PATCH v4 58/80] drm/omap: pll: fix iteration loop check

If the PLL calc function is given bad parameters, n_start/m_start may be higher than n_stop/m_stop, which leads to the loops iterating through the whole u32 number space. Fix this by failing early on such cases. Signed-off-by: Tomi Valkeinen --- drivers/gpu/drm/omapdrm/dss/pll.c | 6 ++ 1 f
