Hi Sakari, Thanks for the review. [...]
+static void led_clamp_align(struct led_flash_setting *s) +{ + u32 v, offset; + + v = s->val + s->step / 2; + v = clamp(v, s->min, s->max); + offset = v - s->min; + offset = s->step * (offset / s->step);You could use the rounddown() macro. I.e. rounddown(v - s->min, s->step) + s->min;
I took this code snippet from v4l2-ctrls.c. It allows for aligning the control value to the nearest step - top or bottom, whereas rounddown only to the bottom one.
