      Pull i2c fixes from Wolfram Sang:
       "The ismt driver had a problem with a rarely used transaction type and
        the designware driver was made even more robust against non standard
        ACPI tables"

      epoll: fix race between ep_poll_callback(POLLFREE) and ep_free()/ep_remove() · 138e4ad6
      Oleg Nesterov authored
      The race was introduced by me in commit 971316f0 ("epoll:
      ep_unregister_pollwait() can use the freed pwq->whead").  I did not
      realize that nothing can protect eventpoll after ep_poll_callback() sets
      ->whead = NULL, only whead->lock can save us from the race with
      ep_free() or ep_remove().
      
      Move ->whead = NULL to the end of ep_poll_callback() and add the
      necessary barriers.
      
      TODO: cleanup the ewake/EPOLLEXCLUSIVE logic, it was confusing even
      before this patch.
      
      Hopefully this explains use-after-free reported by syzcaller:
      
      	BUG: KASAN: use-after-free in debug_spin_lock_before
      	...
      	 _raw_spin_lock_irqsave+0x4a/0x60 kernel/locking/spinlock.c:159
      	 ep_poll_callback+0x29f/0xff0 fs/eventpoll.c:1148
      
      this is spin_lock(eventpoll->lock),
      
      	...
      	Freed by task 17774:
      	...

      	 ep_free+0x22c/0x2a0 fs/eventpoll.c:865
