[igt-dev] [PATCH i-g-t v2 01/17] tools/intel_vbt_decode: Fix mipi sequence block size

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The v3+ MIPI sequence block version number and new size
field are considered part of the BDB block header, and thus
not included in the reported size. Bump up the size appropariately
so that we copy the whole block.
