watchdog: Remove BKL from rio watchdog driver
cycle_kernel_lock() was added with the BKL pushdown. The rio driver indeed needs that because riowd_device is initialized after misc_register(). So an open(), write/ioctl() which happens to get between misc_register returning and riowd_device initialization would dereference a NULL pointer. Move riowd_device initialization before misc_register() and get rid of cycle_kernel_lock(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
