This patch does convert ioctl call to unlocked_ioctl form.
It is possible (in that simple way) due to a spinlock protection.

This patch converts ioctl call to unlocked_ioctl form with
explicit big-kernel-lock. Also it makes a bit of cleanup
converting miscdevice structure initialization to C99 form.
