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().
