Subject: Re: [PATCH] omap drm: fix compile errors where the conversion from
 omap_timing to videomode was not perfect

I did compile and boot tests after each patch when doing the conversion,
but this certainly skipped because these were 'hidden' by
#ifdef PRINT_VERBOSE_VM_TIMINGS

which is not a Kconfig option and needs to be enabled in the dsi.c on
purpose.

Thank you for finding it and sorry for the inconvenience.
