To avoid duplicate logic for the same
How about:
Use drm_display_mode_to_videomode to avoid duplicate logic.

I don't think this is needed here.
But probably drm/drm_modes.h is, since that is where drm_display_mode_to_videomode is declared...

Remove space between int and index.

Drop that comment, it is not really helpful.
- drm_display_mode_to_videomode(mode, &vm);
- clk_set_rate(fsl_dev->pix_clk, vm.pixelclock);
Add newline here.
I like the patch! Thanks!
