You are saying "except" but in at least two cases in this patch you
removing the following text: "retain the above copyright notice, this
list of conditions and the following disclaimer." Aren't it should be
retained?

Also, in one case below you skip dual-licensing in SPDX record.

Cam you also state in the commit message the reason why you are removing
existing license texts at all and not just adding SPDX?
