[ Upstream commit 8e96729fc26c8967db45a3fb7a60387619f77a22 ]

ccree_init() calls cc_debugfs_global_fini(), the former is an init
function and the latter an exit function though.

A modular build emits:

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

(with CONFIG_DEBUG_SECTION_MISMATCH=y).
