Only Linaro can answer what happened up to 2018, as this driver 
originally came from a Linaro tree, which has exactly one commit
for this driver:

	https://github.com/96boards-hikey/linux/commit/08464419fba2417aa849fce976fac9c5f51b3ada#diff-604ef8563dcd9ace6e3e58aac38337c72924b0889f6972d7ee9e15e2335ba964

After merged upstream at staging, all changes are covered by the
Huawei's copyright (2020-2021).

So, I'll just drop this patch. If the information is not accurate,
someone from the original copyright holders can send followup
patches.

Thanks,
Mauro
