If anyone has any objections, please let me know. ------------------ From: Sakari Ailus commit 660e613d05e449766784c549faf5927ffaf281f1 upstream. The ccs_pll_calculate() function does a search over possible PLL configurations to find the "best" one. If the sensor does not support odd pre-PLL divisors and the minimum value (with constraints) isn't 1, other odd values could be errorneously searched (and selected) for the pre-PLL divisor. Fix this.
