Commit ed7e63a51d
has tried to fix
section mismatch:
WARNING: vmlinux.o(.init.text+0x17278): Section mismatch: reference to
.exit.text:uec_mdio_exit (between 'ucc_geth_init' and 'uec_mdio_init')
But that mismatch still happens.
This patch actually fixing section mismatch by removing __exit from
the header file.
