Drop this and all other exports. Nothing here explains the need for them.

Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.

Checkpatch is preerquisite. Don't send patches which have obvious issues
pointed out by checkpatch. It's a waste of reviewers time.

No, no such messages.
