You changed local variable name from 'mode' to 'm' even through using
adjusted_mode instead.
There would be no any changes if you declared like this, struct
drm_display_mode *mode = adjusted_mode. And seems simple enough and
meaningful more to use 'mode' variable name. Anyway, that is very
trivial issue but is there any reason to use 'm' instead of 'mode'?
