• Most drivers have a field in structure like WDOG_ID wdog;  That must be changed to struct wdog_s wdog;  That changes the field from a pointer to a struct wdog_s to the struct wdog_s storage itself.
• Eliminate all calls to wd_create().   The WDOG_ID is not longer managed by the timing subsystem and the wd_create() interface has been removed.
• The wd_delete() interface has also been removed, but more care will need to be exercised:  wd_delete() also cancels any running timer so, in many case, calls to wd_delete() should be replaced with calls to wd_cancel().  If you are certain that the timer has never been started, then you must remove the call to wd_delete() altogether.  Calling wd_cancel() with an un-started, un-initialized struct wdog_s instance may well cause a fatal crash.
• Replace the first parameter of all remaining wdog function calls from.  For example, replace a call like ret = wd_cancel(priv→wdog) where priv→wdog was type WDOG_ID with the call ret = wd_cancel(&priv→wdog)where priv→wdog is now type struct wdog_s.
