Subject: [PATCH -next] crypto: ccree - Fix section mismatch due to cc_debugfs_global_fini()

cc_debugfs_global_fini() is marked with __exit now, however it is used
in __init ccree_init() for cleanup. Remove the __exit annotation to fix
build warning:

WARNING: modpost: drivers/crypto/ccree/ccree.o: section mismatch in reference: init_module (section: .init.text) -> cc_debugfs_global_fini (section: .exit.text)

Fixes: 4f1c596df706 ("crypto: ccree - Remove debugfs when platform_driver_register failed")

This is real issue, right?

"WARNING: modpost: drivers/crypto/ccree/ccree.o: section mismatch in
reference: init_module (section: .init.text) -> cc_debugfs_global_fini
(section: .exit.text)"


Looks like the committer of the patch without building submitted the patch.
4f1c596df706 ("crypto: ccree - Remove debugfs when platform_driver_register failed")

Cheers,
Biju
