Sure, no problem.

Btw. I've noticed minor detail, since the detailed 1 timings live in a separate
function now - the block id 0x03 is reported as unhandled:

> [    0.751759] [drm:drm_parse_display_id] block id 0x3, rev 0, len 60
> [    0.751760] [drm:drm_parse_display_id] found DisplayID tag 0x3, unhandled
> [    0.751760] [drm:drm_parse_display_id] block id 0x7, rev 0, len 10
> [    0.751761] [drm:drm_parse_display_id] found DisplayID tag 0x7, unhandled

You may probably want to add empty DATA_BLOCK_TYPE_1_DETAILED_TIMING case to
the drm_parse_display_id() switch. I originally raised the printk() to
DRM_DEBUG_KMS() so that we know there's something more reported by the panel
that we don't parse. This doesn't affect functionality though.
