I'm not quite sure I understand how these are supposed to be used. The only use-case where a struct display_timings is dynamically allocated is for the OF helpers. In that case, wouldn't it be more useful to have a function that frees the complete structure, including the struct display_timings itself? Something like this, which has all of the above rolled into one:
void display_timings_free(struct display_timings *disp) { if (disp->timings) { unsigned int i;
for (i = 0; i < disp->num_timings; i++) kfree(disp->timings[i]); }
kfree(disp->timings); kfree(disp); }
Is there a use-case where a struct display_timings is not dynamically allocated? The only one I can think of is where it is defined as platform data, but in that case you don't want to be calling display_timing_release() on it anyway.
