Prior to commit 29caf9305b6f ("cyclic: Use schedule() instead of
WATCHDOG_RESET()") we had
/* Currently only needed for fs/cramfs/uncompress.c */
static inline void watchdog_reset_func(void)
{
WATCHDOG_RESET();
}
and .outcb was set to that watchdog_reset_func(). Said commit changed
that .outcb to cyclic_run instead of schedule, which would otherwise
match all the other WATCHDOG_RESET replacements done. As the
HW_WATCHDOG case is not handled by cyclic_run, this seems to be an
oversight.
