Thank you for working on this, but for this driver I think it would be better to just have EXPORT_SYMS=yes rather than enumerating and maintaining the list of symbols. Otherwise this will be a headache for the upstream maintainer.

Agreed. Too many symbols to export and I think it is painful to maintain.

if you confirm Rupesh Pilania <rupeshpilania@gmail.com> as the git commit author I'll push this, thanks!

I'll take care of reformatting the commit message for our standard style, such as using the standard PR: 291273 trailer metadata.
