I would suggest you explain the WHY of this patch.  I would have worded 
it something like this:

Intel's version can be stored in 2 bytes, but ASMedia's version requires 
8 bytes.  Extend the 'major' and 'minor' members of the tb_nvm structure 
to support both vendors.

The idea with the changelog below the cutline is supposed to help 
reviewers know what to focus on when reviewing from one patch to another.

In general it's best to specify what changed from which patch to which 
past the cut line.

For example if this was first patch version that introduced the change 
it should be something like:

v6->v7:
  * New patch based on suggestion by Mario
